If two people hit identical tennis balls at the same time, the ball that has the most kinetic energy is the ball that moves at the fastest speed.
<u>Explanation:</u>
The energy possessed by an object by virtue of its motion is called its kinetic energy indicating that only moving objects have kinetic energy. The kinetic energy of an object depends on its speed and mass.
It is given by the expression
where m denotes the mass of the object and v denotes its velocity.
since kinetic energy is directly proportional to the square of the velocity, the kinetic energy of an object increases with its velocity.
Hence an object that moves at the fastest speed will have the most kinetic energy.
Answer:
Rebounding involves a change in the direction of an object; the before- and after-collision direction is different. ... As mentioned above, if cars rebound upon collision, the momentum change will be larger and so will the impulse. A greater impulse will typically be associated with a bigger force.

The wavelength<span> in a </span>longitudinal wave<span> is probably the distance between two consecutive compressions or between two consecutive rarefactions. The amplitude is the maximum displacement from equilibrium. ... The amplitude is the distance from the equilibrium position of the medium to a compression or a rarefaction.</span>
