Question1
A 1.35 kg block is attached to a spring with spring constant 15.0 N/m. though the block is sitting at rest, a student hits it with a hammer and approximately instantaneously gives it a speed of 33.0 cm/s. What is amplitude of the subsequent oscillations? The block's speed at the point where x= 0.75 A?
Question2
A ball of radius 0.200 m rolls with a constant linear speed of 3.60 m/s all along a horizontal table. The ball rolls off the edge and falls a vertical distance of 2.10 m before hitting the floor. What is an angular displacement of the ball as the ball is in the air?
