3) The tension in the rope pulling a water skier is 500N, and the resistive force of the water is 400N. The total mass of the waterskier and skis is 78kg
a) Draw a free-body force diagram for the water skier
(b) calculate the acceleration (c) calculate the resultant force

Anybody wanna ? (picture included? )

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.

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.
