A tennis ball of mass 100 grams is dropped from a height of 2 metres. Calculate its speed just before it hits the ground. In answering this question, you may assume that all of the gravitational potential energy which is initially stored by the ball is transferred to its kinetic store as it falls through the air. Take g = 10 N/kg.
