Extracted text: The reel of rope has the angular velocity w = 3 rad/s and angular acceleration a = 7.5 rad/s? a B 100 mm L. y A Part A Determine the magnitude of the velocity of point B at the instant shown. Express your answer to three significant figures and include the appropriate units. Part B Determine the direction of the velocity of point B at the instant shown. Express your r using three significant figures. O, = °, measured clockwise from the positive x-axis. Part C Determine the magnitude of the acceleration of point B at the instant shown. Express your answer to three significant figures and include the appropriate units. a = Part D Determine the direction of the acceleration of point B at the instant shown. Express your answer using three significant figures. O, = O. measured clockwise from the positive x-axis.
