Pin P is constrained to move along the curve defined by the lemniscate r =(4sin2theta). If the slotted arm OA rotates counterclockwise with a constant angular velocity of thetadot= 2.0 , determine the magnitude of the velocity of peg P when theta= 58. Determine the magnitude of the acceleration of peg P when theta= 58.
