SECTION A
1 Parasailing is an adventure sport. The parasailor is pulled behind a motor boat as shown in
Fig. 1.
Fig. 1 (not to scale)
32°
The tension in the rope connecting the boat to the parasail is 550 N. The parasailor is moving
horizontally at constant velocity.
(a)
(i) Calculate the vertical component of the tension in the rope.
vertical component =........................................................N [2]
(ii) The combined weight of the parasailor and sail is 870 N. Calculate the vertical upwards force
on the parasailor and sail.
vertical upwards force =........................................................N [1]

(iii) Calculate the power required to pull the parasailor and sail through the air at a horizontal velocity
of 5.8 m s–1. Explain your reasoning.
power =............................................................W

(b) Here are some data about the rope that attaches the sail and parasailor to the boat.
diameter = 12.0 mm
Young modulus = 13.2 GPa
length = 240 m
Calculate the extension of the rope when the tension in the rope is 550 N.
extension =.......................................................m [2]
(c) The boat accelerates. State whether the tension in the rope will increase, decrease or remain at
550 N when the parasail is moving at a greater constant horizontal velocity. Explain your
answer.
