A 1.2 kg mass in placed on the end of a 1.4 m string. One end of the string is fixed, creating a simple pendulum. The mass is pulled to the side so that the string makes an angle of 8◦ with respect to the vertical and released from point A at t = 0.
(a) What is the angular frequency of the system? (b) What is the mechanical energy of the pendulum? (c) What is the maximum linear speed of the mass?
