A fraternity brother finds an old bungee cord at a garage sale and is contemplating on having a bungee jump event. He measures the spring constant of the cord (assume it is a linear spring) by applying a 500 N force to it and measuring a stretch of 2.5 m. Your job is to help him estimate how tall the jump tower should be. He knows the cord is L = 40 m long, he expects the cord to stretch d for an average 60 kg guy like himself, and at maximum stretch he wants his feet to still be 10 m above the ground. Determine: a. The maximum distance, d, the cord would stretch if a 60 kg brother jumped from tower height, H. b. The force developed in the cord at his max stretch position. c. Calculate the expected tower height. d. The velocity of the brother 40 m below from the topmost level of the tower.

A childs pogo stick (Fig. P7.69) stores energy in a spring with a force constant of 2.50 104 N/m. At position (x = 0.100 m), the spring compression is a maximum and the child is momentarily at rest. At position (x = 0), the spring is relaxed and the child is moving upward. At position , the child is again momentarily at rest at the top of the jump. The combined mass of child and pogo stick is 25.0 kg. Although the boy must lean forward to remain balanced, the angle is small, so lets assume the pogo stick is vertical. Also assume the boy does not bend his legs during the motion. (a) Calculate the total energy of the childstickEarth system, taking both gravitational and elastic potential energies as zero for x = 0.

Review. This problem extends the reasoning of Problem 41 in Chapter 9. Two gliders are set in motion on an air track. Glider 1 has mass m1 = 0.240 kg and moves to the right with speed 0.740 m/s. It will have a rear-end collision with glider 2, of mass m2 = 0.360 kg, which initially moves to the right with speed 0.120 m/s. A light spring of force constant 45.0 N/m is attached to the back end of glider 2 as shown in Figure P9.41. When glider 1 touches the spring, superglue instantly and permanently makes it stick to its end of the spring. (a) Find the common speed the two gliders have when the spring is at maximum compression. (b) Find the maximum spring compression distance. The motion after the gliders become attached consists of a combination of (1) the constant-velocity motion of the center of mass of the two-glider system found in part (a) and (2) simple harmonic motion of the gliders relative to the center of mass. (c) Find the energy of the center-of-mass motion. (d) Find the energy of the oscillation.
