A student drops a ball of mass 0.20 kg from a height of 1.5 m.
Gravitational field strength = 9.8 N/kg.
.1Which energy store of the ball decreases as it falls?
[1 mark] .2Calculate the energy transferred from this store as the ball falls 1.5 m.
[2 marks] .3Assume all of this energy is transferred to the ball's kinetic store.
Calculate the speed of the ball just before it hits the ground.
