A parachutist of total weight 950 N falls vertically at a constant velocity of 6.5 m / s.
State the size and direction of the resistive (drag) force acting on the parachutist.
size of resistive force: ______
direction of resistive force: ______
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.
size of velocity = ______
scale = ______
