Asmall sphere with mass m is attached to a massless rod of length l that is pivoted at the top, forming a simple pendulum. the pendulum is pulled to one side so that the rod is at an angle θ from the vertical, and released from rest. (a) the pendulum just after it realeasewd. draw vectors representing the force acting on the small sphere and acceleration of the sphere. auracy count! at this point, what is the linear acceleration of the sphere? (b) reapeat part (a) for the instant when the pendlum rod is at an angle θ/2 from the vertical. (c) repeart part (a) for the instant when the pendulum rod is vertical. at this point, what is linear speed of the sphere?
