I need help for part 2 please
1) A pendulum bob of mass m is attached to an ideal string of length L. The other end of the string is attached to a rigid hook. The bob is lifted along a circular are of radius L until it and the string makes an angle with the vertical, as shown. The bob is then released from rest. a) Prediction: If the magnitude of the tension in the string is measured to...
