A ball has a mass of 0.5kg dropped from a clifftop, the ball strikes the sea below at a velocity of 10m/s.
(a)what is the kinetic energy of the ball as it strikes the sea?
(b) what was its potential energy before it was dropped?
(c) from what height was it dropped?
d) A stone of mass 1kg also hits the sea at 10m/s. Repeat stages a, b and c above to find the height from which the stone was dropped.
