A 1.10 kg block is attached to a spring with spring constant 17 N/m. While the block is sitting at rest, a student hits it with a hammer and almost instantaneously gives it a speed of 46 cm/s. A) What is the amplitude of the subsequent oscillations?
B) What is the block's speed at the point where x = 0.25 A?
