A 65 kg person jumps from a window to a fire net 17 m below, which stretches the net 1.2 m . Assume that the net behaves like a simple spring. How much would it stretch if the person jumped from 38 m ?
Homework Answers
Using work energy theorem
We can find the spring constant using the above theorem
Re-arranging the terms
The net would stretch by 1.79m

An 85 kg person jumps from the top of a building. They swing from a 7 meter rope attached to an adjoining building at their same elevation. The adjoining building has a large void in the structure, 4 meters below where the rope is attached. Assuming the rope doesn't stretch and neglecting air resistance, determine the velocity of the person and the tension in the rope just before the rope comes in contact with the face of the adjoining building....

Problem 3.(25 points) Cathy jumps from a fourth-story window to a firefighter's safety net directly below, as shown in the figure. She is moving downward at a speed of 5.0 m/s at the instant she is 15.0 m above the net. A short while later, she makes impact with the net and stretches the net a distance of 1.0 m before coming to rest. Determine the total time Cathy is in motion, from the moment she is 15.0...

A 90 kg student jumps off a bridge with a 8-m-long bungee cord tied to his feet. The massless bungee cord has a spring constant of 400 N/m. You can assume that the bungee cord exerts no force until it begins to stretch. How far below the bridge is the student's lowest point? How far below the bridge is the student's resting position after the oscillations have been fully damped?
