Question

A strongman in a competition must throw a heavy cement sphere as far as he can up into the air. How high must he throw a 65.0kg sphere to give it 2,000J of potential energy?

Answer 1

Answer:

Explanation:

PE = mgh

h = PE/mg

h = 2000/(65.0(9.81))

h = 3.1365168979...

h = 3.14 m

a VERY strong man if he can do that!
