A high jumper with a body weight of 800N exerts a force of 3 kN against the ground during takeoff.
How much force is exerted by the ground on the high jumper?
f=m x a
The Attempt at a Solution
I converted 800n into KN giving me 0.8
I then divided a=3kn/0.8kn
is this right?
if not, how do i fix the issue
