Equal Kinetic Energy for Different Masses?

[kylepetten]

Homework Statement

Explain how a golf ball and a football can have the same kinetic energy even if their masses are different.

Homework Equations

None.

The Attempt at a Solution

A golf ball and a football can have the same kinetic energy even if their masses are different because kinetic energy is a quadratic function of speed.

This is a new topic and I missed a class or two on it so it may be a super easy question but I just wanted to see what you guys and gals think! Thanks!

Well in essence yes, since E_k=1/2mv², they can have the same E_k if they move with different speeds.
