1. The problem statement, all variables and given/known data 39. An object on the end of a spring is set into oscillation by giving it an initial velocity while it is at its equilibrium position. In the first trial the initial velocity is v0 and in the second it is 4v0. In the second trial: A. the amplitude is half as great and the maximum acceleration is twice as great B. the amplitude is twice as great and the maximum acceleration is half as great C. both the amplitude and the maximum acceleration are twice as great D. both the amplitude and the maximum acceleration are four times as great E. the amplitude is four times as great and the maximum acceleration is twice as great 3. The attempt at a solution To me, since initial velocity is 4x as great, it comes to me that the amplitude will be 4x at great since the initial displacement is zero. but the answer is C, why? and how do we determine how much it affects the maximum acceleration by?
