A heavy-duty shock absorber is compressed 4 cm from its equilibrium position by a mass of 500nbspkg. how much work is required to compress the shock absorber 8 cm from its equilibrium position? (a mass of 500 kg exerts a force (in newtons) of 500g, where galmost equals9.8 m divided by s squared.)

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.

Agirl throws a ball. if the ball's acceleration is 12 m/sec/sec and its mass is 0.5 kg, how much force did the girl apply to the ball?
