Question
nment Question 5 Your answer is partially correct. Try again. g straight down, you can be seriously injured if you land stiff-legged. One way to avoid injury is to bend your k ne way to avoid injury is to bend your knees upon landing to reduce the force of the impact. A 83.9-kg man just before contact with the ground has a s magnitude of the average net force that acts on him during this time. (b) When he bends his knees, he comes to a ha average force acting on the man includes both of these forces. Taking into account the directions of the forces, find the magnitu man in part (b). In a stiff-legged landing he comes to a halt in 3.15 ms. Find the 60 s. Find the magnitude of the s on him during this time. (b) When he bends his knees, he comes to a halt in 0.1 of the ground on the man points upward, while the force due to gravity points downward.

Explanation / Answer
c)
letF be the force by floor
For case b)
Fnet = F - mg
1887.75 = F - 83.9 * 9.8
F = 2710 N
Force applied by Floor is 2710 N
