Question: Problem 5: (15 points) A block (mass = 100.00 grams) attached to a horizontal spring is pulled back a certain distance from equilibrium, then released

Problem 5: (15 points) A block (mass = 100.00 grams) attached to a horizontal spring is pulled back a certain distance from equilibrium, then released from rest at t=0s. If the frequency of the block is 0.725 Hz, (a) what is the earliest time after the block is released that its kinetic energy exactly equals one half of its potential energy? (b) what times does the block reaches its maximum speed and at what times does it reach its maximum elongation in the first cycle? f = 0. 725 Hz t = 0 s KE = I PE
