Q1. At time t=0 a grinding wheel has an angular velocity of 28.0 rad/sec. It has the constant angular acceleration of 35.0 rad/sec^2 until a circuit breaker trips at time t=1.80. From then on, the wheel turns through an angle of 433 as it coasts to the stop at constant angular deceleration.

Q2. Batman (mass = 104 kg) jumps straight down from the bridge into a boat (mass = 600 kg) in which a criminal is fleeing. The velocity of the boat is at first +10 m/s. What is the velocity of the boat after Batman lands in it?
