A gyroscope accelerates from rest to 300 rpm in 0.5 seconds. 1. What is its angular acceleration given in rad/s^2?
2. How many revolutions does it make during that time?

Adiver in midair has an angular velocity of 6.0 rad/s and a moment of inertia of 1.2 kg·m2. he then pulls is arms and legs into a tuck position and his angular velocity increases to 12 rad/s. the net external torque acting on the diver is zero. what is his moment of inertia in the tuck position?
