21N.2.SL.TZ0.1b.iii
A ball of mass 0.250 kg is released from rest at time t = 0, from a height H above a horizontal floor.
The graph shows the variation with time t of the velocity v of the ball. Air resistance is negligible. Take g = −9.80 m s−2. The ball reaches the floor after 1.0 s.
(b.iii)
Draw, on the axes, a graph to show the variation with time of the height of the ball from the instant it rebounds from the floor until the instant it reaches the maximum rebound height. No numbers are required on the axes.
