A 0.750 kg block is attached to a spring with spring constant 15 N/m. While the block is sitting at rest, a student hits it with a hammer and almost instantaneously gives it a speed of 35 cm/s.
What is the amplitude of the subsequent oscillations?
What is the block's speed at the point where x = 0.35 A?
