T 0 5 kg 2m 1978B1 A 0 5 kilogram object rotates freely in a vertical circle at the end of a string of length 2 meters as shown above As the object passes through point P at the top of the circular path the tension in the string is 20 newtons Assume g 10 meters per second squared a On the following diagram of the object draw and clearly label all significant forces on the object when it is at the point P b Calculate the speed of the object at point P c Calculate the increase in kinetic energy of the object as it moves from point P to point Q d Calculate the tension in the string as the object passes through point Q
