Chapter 5, Problem 86AP
A daredevil wishes to bungee-jump from a hot-air balloon 65.0 m above a carnival midway. He will use a piece of uniform elastic cord lied to a harness around his body to stop his fall at a point 10.0 m above the ground. Model his body as a particle and the cord as having negligible mass and a tension force described by Hooke's force law. In a preliminary test, hanging at rest from a 5.00-m length of the cord, the jumper finds that his body weight stretches it by 1.50 m. He will drop from rest at the point where the top end of a longer section of the cord is attached to the stationary balloon. (a) What length of cord should he use? (b) What maximum acceleration will he experience?

On the top of an 80 m tall building, there is a spring of 100 N/M were located 6.22 m away from the edge. Meanwhile, you are riding a crate which has negligible mass. You then compress the spring for about 0.87 m. Using your own mass, calculate how far you’ll go if the surface has a coefficient of kinetic friction of magnitude 0.3?
Please answer correctly, comprehensively, and completely. As based on experience, some expert answers were wrong. Thank you.
A 62.0-kg person jumps from rest off a 2.50-m-high tower straight down into the water. Neglect air resistance during the descent. She
comes to rest 1.30 m under the surface of the water. Determine the magnitude of the average force that the water exerts on the diver.
This force is non-conservative.
A worker pushes a 35.0-kg package on a horizontal roller-belt conveyor until it reaches a certain speed. The package then coasts on the horizontal conveyor, all the while slowing down, until it
comes to a complete stop after moving 1.20 m. While the package is coasting on the conveyor, the opposing friction force averages 6.00 N. Use the WET to find the speed of the package
after the worker pushes it and just as it begins to coast.
