21N.2.SL.TZ0.1b.ii
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.ii)
State the acceleration of the ball at the maximum rebound height.
