A 90g ball is tied to a string so that the center its mass hangs 50 cm below the point where the string is tied to a support rod. The ball is pulled aside to a60° angle with vertical and released. As the string approaches vertical, it encounters a peg at a distance x below the support rod. The string then bends around the peg. If the position of the peg is low enough, the ball will move in a circle wrapping the string around the peg. a.) What is the work done by nonconservative force? And the total mechanical energy for the ball as it swing and rotate around the support rod and peg. b.) What is the smallest value of x for which the ball will move in a circle wrapping the string around the peg. Then predict what will happen to the mechanical energy, gravitational potential energy, kinetic energy, speed, and centripetal force when x reaches its minimum value. Set up a mathematical equation that satisfy the condition for minimum x and solve it based on the conditions provided

A ball of mass m is tied to a string and is rotating in a vertical...

A ball of mass m is tied to a string and is rotating in a vertical plane. The string is elastic (it stretches), which causes the path to be elongated vertically rather than perfectly circular. At the top of the path, the speed has the minimum value that still allows the ball to complete its circular path. Find: the length of the string when it makes an angle θ with respect to the horizontal. The following quantities are known: Mass...
