A pendulum consists of a rod of length 2 m and mass 5 kg with a solid sphere of mass 5 kg and radius 0.6 m attached at one end. The axis of rotation is as shown below. What is the angular velocity (in rad/s) of the
pendulum at its lowest point if it is released from rest at an angle of 30° from the vertical? (Enter the magnitude.)

a wheel of radius 0.20 m is mounted on a frictionless horizontal axis. The rotational inertia of the wheel about the axis is 0.40 kgm2. A massless cord wrapped around the wheel’s circumference is attached to a 6.0 kg box. The system is released from rest.When the box has a kinetic energy of 6.0 J, what are (a) the wheel’s rotational kinetic energy and (b) the distance the box has fallen?
A particular horizontal turntable can be modeled as a uniform disk with a mass of 230 g and a radius of 26.0 cm that rotates without friction about a vertical axis passing through its center. The
angular speed of the turntable is 3.00 rad/s. A ball of clay, with a mass of 40.0 g, is dropped from a height of 25.0 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.
