Complete circle around peg after the string catches on peg

Reference no: EM13542129

A ball is attached to a horizontal cord of length L whose other end is fixed. A peg is located at a distance d directly below the fixed end of the cord. The ball is released from rest when the string is horizontal. ? a. If d = 0.75L, find the speed of the ball when it reaches the top of the circular path about the peg. b. Will the ball be able to make a complete circle about the peg if d = 0.5L? (Hint: what speed does the ball need to have at the top of its arc if it is to continue to move in a circle?) What is the minimum distance d such that the ball will be able to make a complete circle around the peg after the string catches on the peg?
