Q1. A hockey stick is swung with an average angular acceleration of 1.5 rad/s2. What is an angular velocity of the stick when it strikes the ball at the end of 0.8 second swing?

Q2. A string is wound tightly around a freely rotating solid disk of mass M and radius R. The free end of string is then attached to a block of mass M, which itself is attached to a vertical spring of spring constant k. The disk is rotated clockwise by some external agent until the spring is stretched from its equilibrium length by distance R equal to the radius of the disk. The disk is held in this position by the finger pushing directly down at the disk's top until it is released.
