A mass m on a frictionless table is attached to a hanging mass M by a cord length l passing through a hole in the table. Find the speed with which m must spin for M to stay at the highest point. If this speedis doubled, what will be the force with which M will press the table ?

A puck is moving in a circle in a circle of radius r_(0) with a constant speed v_(0) on a level frictionless table. A string is attached to the punk, which holds it in the circle, the string passes through a frictionless hole and is attached on the other end to a hanging object of mass M. The puck is mow made to move with a speed v' = 3v_(0) , but still in circle. The mass of the hanging object is left unchanged. The acceleration a' of the punk and the radius r' of the circle are now given by

A block of mass M = 2 kg with a semicircular track of radius R = 1.1 m rests on a horizontal frictionless surface. A uniform cylinder of radius r = 10 cm and mass = 1.0 kg is released from rest from the top point A. the cylinder slips on the semicircular frictionless track. The speed of the block when the cylinder reaches the bottom of the track at B is (g =10ms^(-2))

A small 0.500 kg object moves on a frictionless horizontal table in a circular path of radius 1.00 m. The angular speed is 6.28 "rad"//s . The object is attached to a string of negligible mass that passes through a small hole in the table at the center of the circle. Someone under the table begins to pull the string downward to make the circle smaller. If the string will toler ate a tension of no more than 105 N, what is the radius of the smallest possible circle on which the object can move?

A bucket of mass 8 kg is supported by a light rope wound around a solid wooden cylinder of mass 12 kg and radius 20 cm , free to rotate about its axis. A man holding the free end of the rope with the bucket and the cylinder at rest initially, lets go the bucket freely downward in a well 50 m deep. Neglecting friction, obtain the speed of bucket and angualr speed of the cylinder just before the bucket enters water. Take g = 10 m//s^(2) .
