Q1. A .800 kg block is attached to a spring with spring constant 16.0 N/m. While the block is sitting at rest, a student hits it with a hammer and almost instantaneously gives it a speed of 41.0 cm/s. What is the amplitude of the subsequent oscillations? The block's speed at the point where x= 0.50 A?
