(a)[1]
Show that the ball reaches the ceiling with a speed of $6.0\,\text{m s}^{-1}$.
(b)[2]
Calculate the height of the ceiling above the point where the ball was thrown.
(c(i))[2]
Calculate the increase in gravitational potential energy of the ball as it moves from its starting position to the ceiling.
(c(ii))[2]
Calculate the decrease in kinetic energy of the ball while it is in contact with the ceiling.
(d)[2]
State how Newton’s third law applies to the collision between the ball and the ceiling.
(e)[2]
Calculate the change in momentum of the ball during the collision.
(f)[2]
Determine the magnitude of the average force exerted by the ceiling on the ball during the collision.
