Question

Andrea and the other members of the tennis team are practicing hitting tennis balls. If two people hit identical balls at the same time, which ball has the most kinetic energy?
A.
the ball that stops moving first
B.
the ball that travels the farthest distance from the ground
C.
the ball that lands the shortest distance away
D.
the ball that moves at the fastest speed

Answer 1

Answer:

D

Explanation:

The formula for calculating kinetic energy is 1/2mv^2, where m is the mass and v is the velocity or speed of the object. Since all of the balls have the same mass, the one with the highest speed or velocity will have the highest kinetic energy. Hope this helps!
