Q. No. 3 A parachutist of total weight 950 N falls vertically at a constant velocity of 6.5
m/s.
(a) State the size and direction of the resistive (drag) force acting on the
parachutist

-size of resistive force:

-direction of resistive force:

(b) At a certain height, the wind starts to blow and the parachutist moves
horizontally at a velocity of 4.5 m/s as he continues to fall. Use a graphical
method to add together the horizontal and the vertical velocities to determine the
size of the resultant velocity of the parachutist. Label the velocities and state the
scale that you use.
