Homework Statement
A 65 kg man jumps at a velocity of 1.8 m/s. The contact time is 0.45 seconds. Find the average force exerted by the man.
Homework Equations
F=ma+mg
The Attempt at a Solution
F=65*(1.8/.45)+65*9.81
I'm not sure if the equation has to be divided by the contact time, .45 seconds, to obtain the average force acting on the man.
