(a)[3]
The hammer has a much greater weight than the feather. Explain, in terms of mass and weight, why both objects have the same acceleration.
(b(i))[2]
Both the feather and the hammer need $1.5\,\text{s}$ to reach the ground after being released from rest. Calculate the speed of the objects when they arrive at the ground.
(b(ii))[1]
On Fig. 1.1, draw the speed-time graph for the descent. At the right location on the y-axis, write the speed value at time $t = 1.5\,\text{s}$.
(b(iii))[2]
From the speed-time graph in (b)(ii), determine the height from which the objects were dropped.
