Jibari walks 40.0 meters east in 120.0 seconds. He then walks 30.0 meters west in 60.0 seconds. What is his average velocity for the trip?

Answers

Answer 1

Answer:

0.1667 meters/second.

Explanation:

To find Jibari's average velocity for the trip, we need to first calculate his average velocity for each leg of the trip. To do this, we need to divide the distance he traveled by the time it took him to travel that distance.

For the first leg of the trip, Jibari walked 40.0 meters east in 120.0 seconds. His average velocity for this leg of the trip is therefore 40.0 meters / 120.0 seconds = 0.3333 meters/second east.

For the second leg of the trip, Jibari walked 30.0 meters west in 60.0 seconds. His average velocity for this leg of the trip is therefore 30.0 meters / 60.0 seconds = 0.5000 meters/second west.

To find Jibari's average velocity for the entire trip, we need to add the velocities for each leg of the trip, taking into account their direction. Since the first leg of the trip was east and the second leg was west, we can simply add the two velocities together to find the overall average velocity.

Jibari's overall average velocity for the trip is therefore 0.3333 meters/second east + 0.5000 meters/second west = 0.1667 meters/second.

Therefore, Jibari's average velocity for the trip was 0.1667 meters/second.

Answer 2

Jibari's average velocity for the trip is 0.7 m/s east.

To solve for Jibari's average velocity, we will first need to find his total displacement. We can do this by adding the magnitudes of his eastward and westward displacements. The magnitude of Jibari's eastward displacement is 40.0 meters, and the magnitude of his westward displacement is 30.0 meters. So, his total displacement is

40.0 - 30.0 = 10.0 meters east.

We can then find Jibari's average velocity by dividing his total displacement by the total time it took him to complete the trip. The total time it took Jibari to complete the trip is

120.0 + 60.0 = 180.0 seconds.

So, his average velocity is

10.0 / 180.0 = 0.7 m/s east.

An object is thrown down from a tall building with an initial velocity of 2 m/s. How fast is it going after 5 seconds of free fall?

Answers

Answer:    Vf = Vi + A(t)

Vf= -2+ (-9.8)(5)

Vf = -51 m/s

Explanation:

The final velocity is equal to the initial velocity plus the acceleration multiplied by the time

(-9.8) is used for the acceleration for this question because that is the speed at which things in free fall accelerate when they are on earth

-2 is used as the initial velocity because the ball was thrown in the negative direction which is down.

What is tension?

Tension is a feeling of tightness, stress, or strain resulting from physical, mental, or emotional conflict. It is a state of being that can be caused by both positive and negative experiences. Tension can manifest itself in physical symptoms such as headaches, muscle tightness, and fatigue. It can also manifest itself emotionally in a sense of unease, worry, and anxiety. Tension can be both a healthy and unhealthy emotion. It can be a warning sign of danger or a motivator to take action. It can also be a sign of stress and can lead to feelings of helplessness or depression. Generally speaking, learning to recognize tension and finding ways to manage it is an important part of maintaining mental and physical well-being.

Find the maximum height and range for vo = 10 m/s, θ = 30°, and Δdy = 1 m. The displacement Δdy corresponds to the stage of the projectile flight where it is moving downward. What is the flight time?

Answers

The maximum height of the projectile is 1.28 m, the range is 5.1 m, and the flight time is 6.066 seconds.

To find the maximum height and range of a projectile with initial velocity vo, launch angle θ, and displacement Δdy, we can use the following equations:

Maximum height: h = (vo²sin^2(θ)) / (2 × g)

Range: R = (vo² sin(2θ)) / g

where g is the acceleration due to gravity (g = 9.8 m/s² on Earth).

As per the question, the maximum height and range of the projectile are given by:

Maximum height: h = (10² × sin²(30)) / (2 × 9.8) = 25 / 19.6 = 1.28 m

Range: R = (10² × sin(60)) / 9.8 = 50 / 9.8 = 5.1 m

To find the flight time of the projectile, we can use the following equation:

Flight time: t = 2 × vo × sin(θ) / g

In this case, the flight time of the projectile is given by:

Flight time: t = 2 × 10 × sin(30) / 9.8 = 6.066 seconds.

Therefore, the maximum height of the projectile is 1.28 m, the range is 5.1 m, and the flight time is 6.066 seconds.

In 1990 Walter areole of Belgium lifted a 281.5-kg object through a distance of 17.1 cm using only his teeth, the total force is 2.76 kN.

What is force?

An object having mass changes its velocity in response to a push or pull. Force is an external agent that has the power to alter a body's resting or moving condition. It has a size and a movement.

What is distance?

The entire movement of an object, regardless of direction, is called distance. Distance can be characterized as the quantity of ground covered, regardless of the starting or finishing points of an object.

a)Work done = m*g*h

where g = acceleration of gravity = 9.8 m/s2

h = 17.1 cm = 0.171 m

So, W = 281.5*9.8*0.171 = 471.8 J

b)Total force exerted,

F = mg = 281.5*9.8 = 2758.7 N = 2.76 kN

Because photons have no mass, they always travel at the speed of light in vacuum, which is 299792458 m/s (or approximately 186,282 mi/s). The photon is a boson.

Photons, like other fundamental particles, are best explained by quantum physics and display wave-particle duality, or behaviour that exhibits traits of both waves and particles.

What is centripetal acceleration?

Acceleration is a physical quantity measuring the rate of change in velocity. It has both magnitude and direction.

Centripetal acceleration is the acceleration of an  object moving through a circular path. Thus its measures the rate of change in velocity of the body moving in the curvature path.

The centripetal acceleration = V²/R.

Where R is the radius of the curvature path.

The car moves 50 m in 9 seconds. Its velocity is 50/9 = 5.5 m/s.

Thus, centripetal acceleration = (5.5 × 5.5) m/s/ 50 m = 0.6 m/s².

Answers

For constructive interference between point A and B, it must be at a distance. 2.5m from  source A.

For destructive interference, it must be at a distance 1m from A or 4m from B

What is interference in radio waves?

it occurs when unwanted radio frequency signals disrupt the use of your television, radio, or cordless telephone. Interference may prevent reception altogether, may cause only a temporary loss of a signal, or may affect the quality of the sound or picture produced by your equipment.

Now, let's try to answer the question 1.

for constructive interference, the path distance will be 0 (zero)

So it must be equally divided distance from both source's distance.
distance between radio waves A and B = 5m apart

For constructive interference = 5m / 2 = 2.5m

Therefore, it must be at a distance 2.5m from A and B.

Moving on to question 2.

for destructive interference, we are using the formula for path difference

path difference = lambda / 2 = 6m / 2 = 3m

given from question

lambda (wavelength) = 6m

Let the distance from A as Z

Then, the distance from B will be 5-Z

Path difference = 5-Z-Z

3 = 5 - 2Z

Z = 1m

The distance from A = 1m

The distance from B = 5 - 1 = 4m

Therefore, for a destructive interference, it must be at a distance 1m from A, or 4m from B.

f the perimeter of the window is 16 feet, find the exact value of x (in ft) so that the greatest possible amount of light is admitted.

Answers

The perimeter of the window is 16 feet, find the exact value of x (in ft) so that the greatest possible amount of light is admitted is 37.278 feet.

What is perimeter?

The area surrounding a shape's edge is known as its perimeter. By multiplying the side lengths of various forms, one can determine their perimeter.

What is light ?

The electromagnetic radiation known as light is what enables the human eye to see and makes things visible. It can also be described as radiation that can be seen by humans. Light is made up of small energy packets called photons.

perimeter = 16

x+2h+πx/2= 16

h= 8-x/2- xx/4⇒1

maximize

Area;

A= xh+π(x/2)²/2

A= xh+π x²/8

Pu + h = 8-x/2 - xx/4

A= x(8-x/2 - xx/4 ) +π/8 x²

A= 8x- x²/2 - x²/4 +xx²/8

Differentiate with respect to "x"

dA/dx = 8x-1 -π/4*2x²+π/8*2x²⁻¹

dA/dx = 8-x-π/2 x+π/4 x

dA/dx= 8- (1-π/2 +π/4 ) x

For maximum

Solve dA/dx=0

= 8-(1-π/2+π/4)x =0

x= -8/-(1-π/2+π/4)

x= 37.278 feet

Therefore, the perimeter of the window is 16 feet, find the exact value of x (in ft) so that the greatest possible amount of light is admitted is 37.278 feet.
