7. A uniform rod of length L and mass M is attached at one end to a frictionless pivot and is free to rotate about the pivot in the vertical plane, as shown below. The rod is released from rest in the horizontal position. (a) Using conservation of energy, find the angular speed of the rod when it reaches its lowest position. (b) Assume a bug of mass "m" is sitting on the edge of the rod when it was released, what would the bug's translational speed be when the rod reaches the lowest point?

A 0.643 kg cat sits at the end of a 15.7 kg, 11.2 m long beam. An accident occurs and the support cable breaks, causing the beam to rotate without friction until it hits the wall. If the cat held onto the end of the beam what would its speed be as it impacts the wall? (however, it is smart and jumps off part way down)
A 26 g block sits at the center of a turntable that rotates at 50 rpm. A compressed spring shoots the block radially outward from the center along a frictionless groove in the surface of the turntable. Calculate the turntable's angular speed when the block reaches the outer edge. Treat the turntable as a solid disk with mass with mass 200 g and diameter 30.0 cm. Express your answer in revolutions per minute.
Two masses, m1 =15 kg, m2 = 3kg in Atwood's machine are connected over the frictionless pulley that is a uniform disk with a radius of 12cm. The mass of the pulley is 0.2 kg. Use conservation of energy to solve for the final speed of block m1 and m2, when the block m2 moves down a distance of 1.2 m.
