A ball is held above the ground and released. It falls to the ground and bounces several times. The graph shows the variation with time t of the velocity v of the ball. Four points on the graph are labelled P, Q, R and S. Which statement is not correct?

1. AThe area under line PQ represents the initial height of the ball.
2. BThe collisions of the ball with the ground are inelastic.
3. CThe gradient of the line RS represents the acceleration due to free fall.
4. DThe maximum upwards velocity of the ball is reached at point P.
