(a)[1]
Define acceleration as the rate at which velocity changes.
(b(i))[2]
Calculate how long object A takes to hit the ground.
(b(ii))[2]
Use your answer from (b)(i) to find $u$.
(c(i))[2]
State and explain whether the time taken for object B to reach the ground is less than, the same as or greater than the time in (b)(i).
(c(ii))[2]
By considering energy, state and explain the effect of the change in release angle on the speed at which B reaches the ground.
