A1.2 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 maximum angular velocity of the pendulum? (c) what is the maximum linear speed of the mass? (d) at which point is the magnitude of the angular acceleration greatest? i. b ii. c iii. d
