Abucket hangs from a rope that is attached to a cylindrical, massive pulley with a radius of 0.540 m and a mass of 2.22 kg. the pulley spins as the bucket falls, undergoing an angular the bucket starts at rest and falls a distance 5.51 m before hitting the water. during this time the pulley undergoes an angular acceleration of 3.19 rad/s2, which means the bucket is falling with a linear acceleration of 1.72 m/s2 (a=

1. what is the moment of inertia of the pulley? (remember, this is a solid cylinder.)

2. what is the magnitude of the torque that the rope exerts on the pulley? (think about the rotational version of newton's second law.)

3. since you know the torque, what is the force that the rope is exerting on the pulley?

4. how much time elapses between when the bucket is released and when it hits the water?

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
