A toddler with a mass of 15.2 kg bounces up and down in her crib. The crib mattress behaves like a light spring with force constant 726 N/m. (a) The toddler bounces with at a frequency that allows her to reach a maximum amplitude with minimum effort. What is this frequency (in Hz )? Hz (b) The toddler now bounces high enough to lose contact with the mattress once each cycle, like a trampoline. What is the minimum amplitude of oscillation (in cm ) required for this to occur? cm

A 71.5 kg bungee jumper is standing on a tall platform (h0 = 55 m), as indicated in Figure 10.36. The bungee cord has an unstrained length of L0 = 9 m, and when stretched, behaves like an ideal spring with a spring constant of k = 62.5 N/m. The jumper falls from rest, and the only forces acting on him are his weight and, for the latter part of the descent, the elastic force of the bungee cord. (To simplify the problem slightly, assume the cord is attached at the center of mass and the center of mass drops from rest from the height of the platform. ) Figure 10.36 What is his maximum speed during the fall? m/s How high above the water is he when he reaches this speed? m How high above the water is he when he reaches the lowest point in the fall? m

A 15.0-kg stone slides down a snow-covered hill (Fig. below), leaving point A with a speed of 10.0 m/s. There is no friction on the hill between points A and B, but there is friction on the level ground at the bottom of the hill, between B and the wall. After entering the rough horizontal region, the stone travels 100 m and then runs into a very long, light spring with force constant 2.00 N/m. The coefficient of kinetic friction between the stone and the horizontal ground is 0.20. (a) What is the speed of the stone when it reaches point B? (15) (b) How far will the stone compress the spring? (15)

Radiotherapy devices often utilize linear particle accelerators that require a high voltage pulse. A Marx generator is a circuit that allows the input voltage to be multiplied and delivered to a load i a short period of time. In the circuit shown in the figure, a fixed voltage source is applied between points a and b, and the capacitors are charged in parallel with all four switches open. (a) What is the final charge (in mC) on each of the capacitors when the voltage source is applied across points a and b and all four 5 witches are open? Q1 = mc Q2 = mc Q3 = mc (b) How long does it take for each of the capacitors to reach 99.0% of their maximum charge? t1 = ms t2 = ms t3 = ms (d) What is the initial voltage (in V) across points c and d immediately after all four switches are closed? (e) What is the time interval (in ms) required for the current in the circuit to reach 20.0% of its initial value after all four switches are closed? ms
