Under the action of force P, the constant acceleration of block B is 7.0 ft/sec² up the incline. For the instant when the velocity of Bis 4.0 ft/sec up the incline, determine the velocity of B relative to A (positive if up the slope, negative if down), the acceleration of 8 relative to A (positive if up the slope, negative if down), and the absolute velocity of point C (positive if up the slope, negative if down) of the cable. Answers: VOA - 20 ft/sec ft/sec² ft/sec
