Under the action of force P, the constant acceleration of block B is 7.9 ft/sec? up the incline. For the instant when the velocity of B is 2.0 ft/sec up the incline, determine the velocity of B relative to A (positive if up the slope, negative if down), the acceleration of B 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. 24° Answers: VB/A = ft/sec ft/sec2 aB/A = Vc= ft/sec
