The jumper has a mass of 60 kg, and the bridge's height above the river is 150 m. the rope has an unstretched length of 8 m and stretches a distance of 4 m before bringing the jumper to a stop. determine the maximum speed of the jumper and the spring constant of the rope. in your calculation, use g = 10 n/kg.

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.
