, Answer all the questions.
1. A stunt cyclist rides horizontally off the edge of a cliff at a speed of 18.0 m s⁻¹. The cliff is 45.0 m
above the sea surface below. Air resistance is negligible.
(a) Show that the time taken for the cyclist to reach the sea surface is approximately 3.0 s.
(g = 9.81 m s⁻²)
[2]
(b) Calculate the horizontal distance travelled by the cyclist from the base of the cliff before hitting the
sea.
Horizontal distance = ............................................................. m [2]

, (c) Calculate the magnitude and direction of the cyclist's velocity at the moment of impact with the sea.
Magnitude of the cyclist's velocity = ............................................................. m/s
Direction of the cyclist's velocity = ............................................................. [4]
(d) The cyclist wears a safety helmet. The helmet compresses by 6.0 cm as the cyclist decelerates to
rest on hitting the water. The cyclist's mass is 75 kg.
Calculate the average decelerating force on the cyclist's head during impact.
State one assumption you make.
Average decelerating force = .............................................................N
