29. The total energy is given by Ek x m = 1 2 2 , where k is the spring constant and x m is the amplitude. We use the answer from part (b) to do part (a), so it is best to look at the solution for part (b) first. (a) The fraction of the energy that is kinetic is 13 == 1 = 1 = 0 . 7 5 44 KEU U E EE −−= where the result from part (b) has been used.
