A particular horizontal turntable can be modeled as a uniform disk with a mass of 230 g and a radius of 22.0 cm that rotates without friction about a vertical axis passing through its center. The angular speed of the turntable is 2.00 rad/s. A ball of clay, with a mass of 50.0 g, is dropped from a height of 40.0 cm above the turntable. It hits the turntable at a distance of 15.0 cm from the middle, and sticks where it hits. Assuming the turntable is firmly supported by its axle so it remains horizontal at all times, find the final angular speed of the turntable-clay system.
The pulley system is used to lift a 52 kg crate. Note that one chain connects the upper pulley to the ceiling and a second chain connects the lower pulley to crate. assume the masses of the chains, pulleys, and ropes are negligible, conclude the forc..
