Question

Superman wants to get as much Kinetic energy (KE) as he can when hitting a baseball. He asks you if he should use a slightly heavier bat or if he should swing twice as fast. Which would you recommend to Superman and why?

Answer 1

Answer: Swing twice as fast

Explanation: If superman wants to get a lot of kinetic energy he should swing fast. Kinetic energy is the energy of motion/movement so that means the  more you do something fast the more KE you will get and if you do something twice as fast then you will gain more kinetic energy.
