2/134 Motion of the sliding block P in the rotating radial slot is controlled by the power screw as shown. For the instant represented, 6 = 0.1 rad/s, ô =

-0.04 rad/sº, and r = 300 mm. Also, the screw turns at a constant speed giving † = 40 mm/s. For this instant, determine the magnitudes of the velocity v and acceleration a of P. Sketch v and a if 0 = 120°.
