Striking Speed Ball
A 1.00-kilogram ball is dropped from the top of a building. Just before striking the ground, the ball’s speed ?
A 1.00-kilogram ball is dropped from the top of
a building. Just before striking the ground, the
ball’s speed is 12.0 meters per second. What was
the ball’s gravitational potential energy, relative
to the ground, at the instant it was dropped?
(1) 6.00 J (3) 72.0 J
(2) 24.0 J (4) 144 J
I know the answer is (3) but I don't know how!!!!
Its gravitational potential energy is completely converted to kinetic energy when it hits the ground, that is :
PE (initial) = KE(final)
KE is :
KE = 0.5mv²
= 0.5(1.00kg)(12.0m/s)²
= 72.0J
So gravitational potential energy is 72.0J.
