Question

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 4*v0. In the second trial: A) the amplitude is half as great and the maximum acceleration is twice as great B) both the amplitude and the maximum acceleration are twice times as great C)the amplitude is twice as great and the maximum acceleration is half 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

Explanation / Answer

The amplitude and acceleration is Proportional to v

As v becomes 4 times

Amplitude and velocity becomes 4 = 2 times

C. both the amplitude and the maximum acceleration are twice as great
