Q1. At time a grinding wheel has an angular velocity of 21.0. It has a constant angular acceleration of 26.0 until a circuit breaker trips at time = 1.6. From then on, the wheel turns through an angle of 435 as it coasts to a stop at constant angular deceleration.

Q2. A water skier of mass m = 56.0 kg is pulled behind a boat at a constant speed of 26 mph (in the positive x-direction). If the tension in the horizontal rope is 927 N (approximately 206 lbs), find out the magnitude and direction of the force that the water exerts on the skier's ski.
