A bungee jumper dives from a bridge. At a point near the bottom of his dive, the forces acting on him are:
gravity: 700 N downwards
spring force: 850 N upwards
air resistance: 60 N upwards
Showing your working, calculate:
the net force (strength and direction) acting on him
his acceleration, given that his mass is 70 kg
