Joshua is preparing a report to show the relationship between average kinetic energy and temperature. Is his graph accurate?

When you jump from an elevated position you usually bend your knees upon reaching the ground. by doing this, you make the time of the impact about 10 times as great as for a stiff-legged landing. in this way the average force your body experiences is a) less than 1/10 as great. b) more than 1/10 as great. c) about 1/10 as great.d) about 10 times as great.

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?
