3. A bucket at for collecting water from a well is suspended from a light rope that is wrapped around a pulley with radius r = 10 cm and a moment of inertia of 0.1 kg-m². The empty bucket has a mass of 2 kg. Suppose someone drops the bucket from rest. Use conservation of energy to find how fast the bucket moving right before it hits the surface of the water 3 m below. 10 Note: you need to use that the speed of the bucket, v, is related to the angular speed of the pulley, w, by v = rw. Justify this with a brief explanation.

ω_new,z = -5.841 rad/s R= 2.68 m I_1 = 11.1 kg⋅m2 I_2 = 16.6 kg⋅m2 ω_1,z=10.3 rad/s ω2,z=−15.5 rad/s Starting with ω_new,z you now want to immediately slow the system down, so you decide to throw a mud ball ( m_mud=2.78 kg ) at the system of rotating disks. The trajectory from above looks like this: The mud is moving with initial speed v_mud=18.9 m/s and sticks to the rim of the disk upon impact. The distance d=1.23 m. Find the common final z-component of the angular velocity of the two disks and the mud. As a reminder, positive z-components correspond to counterclockwise rotation.
Figure P9.75 shows a 100 g puck revolving at 100 rpm on a 20-cm-radius circle on a frictionless table. A string attached to the puck passes through a hole in the middle of the table. The end of the string below the table is then slowly pulled down until the puck is revolving in a 10-cm-radius circle. How many revolutions per minute does the puck make at this new radius?

A solid spherical jewel rolls smoothly from rest down a ramp. The jewel descends a vertical height of 1.2m to reach the bottom of the ramp. What is the jewel's speed at the bottom of the ramp? Hint: This problem has nothing to do with elasticity as we did not formally cover that topic, and the inertia of a solid sphere is found by 2/5 m r2

The spin cycle of a clothes washer extracts the water in clothing by greatly increasing the water’s apparent weight so that it is efficiently squeezed through the clothes and out the holes in the drum. In a top loader’s spin cycle, the 45-cm-diameter drum spins at 1200 rpm around a vertical axis. What is the apparent weight of a 1.0 g drop of water?
