A baseball weighs 5.19 . What is the kinetic energy in joules of this baseball when it is thrown by a major-league pitcher at 98.0 ?

• Chem/Physics -

Can you not at least look in your textbook? There just HAS to be a formula for kinetic energy:

K = 1/2 m v^2

You have m and v. What's the problem?

4.726 J
