Instructions Complete the following exercises in class on Wednesday, May 18. Feel free to work together in groups or to consult with your instructor. These exercises are for your bene±t and need not be turned in. Make sure you understand all of the material! 1. Doubling the distance a spring is stretched increases the restoring force by what factor? 2. I push a 12 kg box along a frictionless surface for a distance of 10 m applying a force of 100 N. What work is done during this process? 3. Calculate the maximum potential energy of a mass-spring system with a spring constant of k = 100 N/ m and an attached mass of 5 kg if its maximum displacement is 5 cm. 4. A 2 kg box slides down a frictionless incline as illustrated. determine its speed at the bottom of the incline if it started at the top from rest. 5. One marble is twice as heavy as another. ey are dropped to the ground from the roof of a building. Just before striking the ground, what is the ratio of the kinetic energy of the heavier to the lighter?
