The peg is constrained to move in the slots of the fixed bar CD and rotating bar

Question

The peg is constrained to move in the slots of the fixed bar CD and rotating bar AB. When theta = 30degrees , the angular velocity and angular acceleration of arm AB are thetadot= 2rad/sec and thetadoubledot= 3rad/sec^2 , respectively.
a)Determine the magnitude of the velocity of the peg P at this instant.

b)Determine the magnitude of the acceleration of the peg P at this instant.

Please your answer should be ft/sec and ft/sec^2 respectively.
