On a windy day, a parachutist of mass 85 kg jumps from an aeroplane.
Fig. 3.1 shows the parachutist falling through the air at a constant vertical velocity of 8.4 m / s downwards.
As the parachutist falls, the wind is moving him towards the right of the diagram, at a
horizontal velocity of 6.3 m / s.
(i) On Fig. 3.1, draw an arrow to show the horizontal velocity of the parachutist.
(ii) On the grid below, draw a vector diagram to determine graphically the size and
direction of the resultant velocity of the parachutist.
