Given what we know, if a golf ball and a ping-pong ball both move with the same kinetic energy, the ping-pong ball must be traveling at a greater speed.

How do we know that the ping-pong ball is faster?

This has to do with the formula for kinetic energy.
The formula is [tex]KE= 1/2 *m * v^2[/tex].
This means that mass and velocity are proportional.
If the total Kinetic energies are equal, the object with the lower mass must have a higher velocity.
Since ping-pong balls are known to have very little mass, we know it must be traveling faster.

Therefore, we can confirm that if a golf ball and a ping-pong ball both move with the same kinetic energy, the ping-pong ball must be traveling at a greater speed due to its lower mass and the relationship between mass and speed when calculating kinetic energy.
