Question

A 7.0 kg bowling ball moves at 2.00 m/s. How fast must a 2.80 g Ping-Pong ball move so that the two balls have the same kinetic energy? m/s

Answer 1

Answer #1

Given,

Let the velocity of the ping-pong ball be 'v'

We know that Kinetic energy (K) is given by,

The ping-pong ball should have the same kinetic energy as that of the bowling ball,

that is;

Hence, the ping-pong ball should move with a velocity of 100 m/s to have the same kinetic energy as that of the bowling ball.
