A simple pendulum consists of a 2.0 kg bob attached to a light string 3.0 m in length. While hanging at rest with the string vertical, the bob is struck sharply giving it a horizontal speed of 4.5 m/s. When the string makes an angle of 30 with the vertical find a) its speed and the tension in the string. b) What is the angle of the string with the vertical when it reaches its highest point?
