The sports car will have more kinetic energy as it has more mass than a minivan.

The equation for Kinetic Energy is

KE = 1/2 mv2.

Kinetic energy has a direct relationship with mass, meaning that as mass increases so does the Kinetic Energy of an object.

Due to its higher mass than a minivan, the sports vehicle will contain more kinetic energy.

Kinetic energy, which may be seen in the mobility of an item or nuclear particle, is the fuel of motion. Kinetic energy is present in every particle and moving thing. Illustrations of kinetic energy in action include a person walking, a baseball soaring through the air, a piece of food sliding from a table, and then a charged molecule in an electric field.

An object's kinetic energy multiplies by four when its speed doubles. The Greek word "kinesis," which implies motion, is where the word "kinetic" originates. A collision is one way that kinetic energy may be transmitted from one item to another.

The damping frequency is 12.68 rad/s.

Given data

mass = 250 kg

damping ratio = 0.2

to find out

damped natural frequency of the system

solution

we first find the natural frequency that is express as

natural frequency ω = √k/m    ..............1

here k is stiffness and m is mass

so ω = √3000/250 = √120

ω = 12.95 rad/s

If the forces acting on an object are balanced, so it doesn't cause a change in motion.

1. Force on a stationary object

This force occurs when there is an impulse that is done in the opposite direction with the same force. Then each object emits a force. But because the directions of the forces are opposite to each other, the total force becomes smaller or cancels each other out.

2. Force on moving objects

In this style, when two people push an object together, the position of the object can shift. That's when there is motion caused by more than one force. The forces on objects become mutually reinforcing, so the resulting force becomes greater. Forces that are in the same direction will increase the total force.

3. Force on an object that causes a change in the direction of motion

When someone rides a bicycle then turns the direction of movement. It happens that there is a tensile force and muscle force that deflects the bicycle handlebar. When playing the ball can change the direction of the ball caused by kicks, throws, or punches from players. Then the player exerts a force on the ball that causes the ball to change direction.

define distance ?

Distance is a numerical or sometimes qualitative measurement of the distance between objects or points. In physics or everyday use, distance can refer to physical length or estimate based on other criteria (e.g. "two particles above"). Since spatial perception is a rich source of conceptual metaphors in human thought, the term is also often used metaphorically to refer to a measure of the degree of difference between two similar objects ( such as the statistical distance between probability distributions or the distance between text strings) or the degree of separation (as illustrated by the distance between people in a social network). Most concepts of distance, both physical and metaphorical, are formalized in mathematics using the concept of metric space.

m = 4.5 kg is the mass of a cement block.

The block raises the vertical distance by d=1.2m.

d' = 7.3 m is the horizontal distance covered by the block.

Since the person raises the block, there is some displacement of the block. As a result, the individual will accomplish good job. And the person's work is saved in the form of block potential energy.

w=mgd

=4.5x9.8x1.2

=52.92 J

As the gravity will oppose the block's motion, thus it will produce negative work on the block. Therefore,

The CMB is faint cosmic heritage radiation filling all areas. it's far a vital source of records of the early universe because it's by far the oldest electromagnetic radiation within the universe, dating to the epoch of recombination when the primary atoms were fashioned. With a conventional optical telescope, the distance between stars and galaxies (the heritage) is absolutely dark (see: Olbers' paradox). but, a sufficiently sensitive radio telescope indicates a faint heritage brightness, or glow, nearly uniform, that is not associated with any megastar, galaxy, or different item. This glow is most powerful in the microwave region of the radio spectrum.

CMB is landmark proof of the large Bang origin of the universe. when the universe become younger, before the formation of stars and planets, it turned denser, lots warmer, and full of an opaque fog of hydrogen plasma. because the universe elevated the plasma grew cooler and the radiation filling it extended to longer wavelengths. whilst the temperature had dropped enough, protons and electrons blended to shape impartial hydrogen atoms. not like the plasma, those newly conceived atoms couldn't scatter the thermal radiation with the aid of Thomson scattering, and so the universe has become obvious.

The gravitational acceleration at altitude h above the earth's surface is g.R^2/(R+ h) ^2.

In physics, gravitational acceleration is the speed at which a body falls freely in a void (and thus without experiencing drag). This is the constant acceleration brought on just by the gravitational pull. Gravimetry is the measurement and study of these rates. All bodies accelerate at the same rate in vacuum, independent of their masses or compositions.The combined effects of gravity and the centrifugal force from Earth's rotation determine the strength of Earth's gravity at a fixed place on its surface.

Let, gₙ be the acceleration due to gravity at height h.

gₓ be the acceleration due to gravity at depth x.

The acceleration due to gravity on the surface of Earth is

g= GM/R^2

where,R is the radius of Earth,M is mass of Earth and G is gravitational constant.

∴g ∝ 1/R^2

gₙ ∝ 1/(R+ h) ^2

 The maximum height the object reaches is [tex]\frac{v^{2} sin^{2}x}{2g}[/tex].

When a particle is hurled obliquely near the surface of the earth, it travels along a curved route while accelerating continuously in the direction of the planet's centre (we assume the particle stays close to the surface of the globe). Such a particle's motion is known as projectile motion, and its route is referred to as a projectile. When a particle is sent into the air at a certain speed, the only force acting on it is the acceleration caused by gravity (g). This downward vertical acceleration has an effect. The fact that there is no acceleration in the horizontal direction indicates that the particle's horizontal velocity stays constant.

The highest vertical location along the object's flight is considered to be its greatest height. The range of the bullet is defined as its horizontal displacement.

A mass is connected to a spring and is allowed to move horizontally. The mass is at a position L when the spring is unstretched. The mass is then moved, stretching the spring, and released from rest. It then moves with simple harmonic motion.

At that instant instantaneous acceleration is 0.

If an object's velocity changes, it is said to have been accelerated. An object's velocity can alter depending on whether it moves faster or slower or in a different direction. A falling apple, the moon orbiting the earth, and a car stopped at a stop sign are a few instances of acceleration. Through these illustrations, we can see that acceleration happens whenever a moving object changes its direction or speed, or both.

Since acceleration has both a magnitude and a direction, it is a vector quantity. It is also the first derivative of position with respect to time or the second derivative of position with respect to time.

ΔK.E. = 1 ÷ 2 × 70 × (4)²

ΔK.E. = 35 × 16

ΔK.E. = 560 Joules

560 Joules of mechanical energy

b. To gauge the runner's slide's distance:

We would first determine the runner's acceleration.

Acceleration = ug

Acceleration = 0.70 × 9.8

Acceleration = 6.86 m/s²

For distance,

V² + U² = 2as

4² + 0² = 2(6.86)s

16 = 13.72s

Distance, S = 1.2 meters.
