Suppose the mower is moving at 1. 5 m/s when the force f is removed. How far (in m) will the mower go before stopping?.

Small sports car will experience a larger change in kinetic energy during inelastic collision.

In inelastic collision we know that loss of energy is possible. It means law of conservation of energy is not possible. An inelastic collision is an impact where there is a deficiency of motor energy. While force of the framework is moderated in an inelastic collision, motor energy isn't. This is on the grounds that some dynamic energy had been moved to something different. Nuclear power, sound energy, and material distortion are reasonable offenders.

Car has small mass as compared to a massive tractor. Due to its high mass car have greater speed as compared to massive tractor. During inelastic collision when a small mass car is collided with large massive tractor ,it transfers most of its energy to a massive tractor and lost that energy in form of heat.

Hence, a small sports car experience a larger change in kinetic energy.

A truck is traveling at speed of 15 m/s on a slippery road. It will travel a distance of 57.4 meters before finally stop.

Using the Newton's 2nd law of motion:

Fs = m . a

Where:

Fs = friction force

m = mass of the truck

a = acceleration

Fs = μ . N

    = μ . mg

Where:

μ = coefficient of kinetic friction the tires and the road = 0.2

N = normal force = m . g

Hence,

μ . mg = m . a

a = μ . g

  = 0.2 x 9.8 = 1.96 m/s²

Using the equation of motion for a decelerated motion:

v² = u² - 2as

Where:

v = final speed = 0 (since the truck finally stop)

u = initial speed

s = distance

Hence,

0 = 15² - 2 x 1.96 x s

s = 225 / 3.92 = 57.4

Resolving scaling factor you find the image vertices for dilation with center 0 0

Magnification is defined as a number or conversion factor used to change the size of a shape without changing its shape. Used to increase or decrease the size of an object. If you know the dimensions of the original shape and the dimensions of the enlarged (scaled up or down) shape, you can calculate the scale factor.

For example, a rectangle is 5 units long and 2 units wide. If you scale this rectangle by a factor of two, the sides are 10 and 4 units, respectively. So you can use the scale factor to get the dimensions of the modified figure.

The coordinates of the image vertices can be calculated as follows:

For vertex A (-3, 1) then A' (4 × -3, 4 × 1) = A' (-12, 4)

For vertex B then (4, -3) then B' (4 × 4, 4 × -3) = B' (16, -12)

Rotation curves of spiral galaxies are a measure of the velocity of the stars and gas in the galaxy as a function of distance from the center. These curves are important for understanding the mass distribution of the galaxy, which in turn helps us understand the structure of the galaxy and its evolution.

In order to determine the rotation curves beyond the radii where starlight can be detected, we must use indirect methods. One of the most important indirect methods is the use of neutral hydrogen gas, which is typically found in the outer regions of galaxies. By measuring the Doppler shifts of the hydrogen gas using radio telescopes, we can determine the velocity of the gas as a function of distance. This allows us to trace the rotation curve out to much larger radii than just the starlight.

Another method for determining the rotation curves beyond the radii where starlight can be detected is to use gravitational lensing. This method relies on the fact that the gravity of a massive object, such as a spiral galaxy, can bend and focus the light from more distant objects. By measuring the distortions of the light from those distant objects, we can infer the mass distribution of the galaxy and thus its rotation curve.

The pulley is initially at rest are:

a) The angular acceleration is 0 rad/s^2.

b) The angular speed is 0 rad/s.

Initially, the acceleration of the pulley is zero. As the pulley starts to move, the acceleration increases until it reaches its maximum value, which is determined by the magnitude of the force applied to it. As the pulley continues to move, the acceleration gradually decreases until it reaches zero again as the pulley comes to rest.

Angular acceleration is the rate at which the angular velocity of an object changes over time. It is usually expressed in terms of radians per second squared (rad/s2). Angular acceleration is caused by a torque being applied to an object and can be used to predict the angular velocity of a spinning object. Angular acceleration is a vector quantity, meaning it has both magnitude and direction.

Angular speed is the rate at which an object rotates or revolves around an axis. It is measured in terms of angle per unit of time and is usually expressed in radians per second (rad/s) or revolutions per second (rpm). Angular speed is related to linear speed, which is the distance traveled per unit of time. The angular speed can be calculated by taking the ratio of the linear speed and the radius of the circular path.

The frequency and amplitude of the SHM beam is 0.8 Hz and 0.098 m. The frequency of the SHM wave when gravel falls is 0.8 Hz and the amplitude of subsequent SHM beam is 0.4m.

(a) Mass of the spring = 225 Kg

Mass of the sack = 175 Kg

Amplitude of the beam = 40 cm = 0.40 m

Frequency of the beam = F = 0.60 cycles/s

The formula for frequency of oscillation =

= f = (1/2π) X √(k/m)

where, k = 2π²F²m

= k = 2 X (3.14)² X 0.6² X (225 + 175)

= k = 5685.37 N/m

Strength of the spring before gravels fall = x =

= x = mg / k

= x = [ (225 + 175 ) X 9.8 ] / 5685.37

= x = 0.689 m

But, the spring is stretched by the distance of x' which is expressed as,

= X = x - x'

= X = 0.689 - 0.40

= X = 0.289 m

Now, since we know that the gravel falls, thus frequency = f =

= f = (1/2π) X √(k/m)

= f= (1/ 2 X 3.14) X √ 5685.37 / 225

= f = 0.8 Hz

(b) Assuming that the spring is stretched, x = mg/k =

= x = (225 X 9.8) / 5685.37

= x = 0.3878 m

Thus, the amplitude of the sack = A = 0.3878 - 0.289

= A = 0.098 m

(c) If the gravel falls, the speed is maximum hence speed = s =

= s = A X √(k/m)

= s = 0.4 X √(5685.37/400)

= s = 1.508 m/s

The frequency = f' =

= f' = (1/2π) X √(k/m)

= f' = (1/2 X 2.14) X √(5685.37/225)

= f' = 0.8 Hz
