Answer to Question #96866 in Classical Mechanics for Abdulkadir Imoro

Question

A parachutist weights 1000N. When she opens her parachute it pulls upwards on her with a force of 2000N.a. draw a diagram to show the forces acting on the parachute. b.Calculate the resultant forces acting on the parachute. C.what effect will this force have on her

Answer 1

(a)

(b) The resultant force

$$F=2000\:\rm N-1000\:\rm N=1000\: N\; (upward)$$

(c) The parachutist will move with constant deceleration

$$a=\frac{F}{m}=\frac{1000\:\rm N}{100\:\rm kg}=10\:\rm m/s^2$$
