An industrial robot is being used to position a small part P. Calculate the magnitude of the acceleration, in mm/s?, of P for the instant when B is 30° if the angular velocity and angular acceleration of ß is 10deg/sec and 20deg/sec?, respectively at this same instant. The base of the robot is revolving at the constant rate of 40 deg/sec. During the motion arms AO and AP remain perpendicular. Round your answer to 2 decimal places. A 300 mm 200 mm
