Under the action of force P, the constant acceleration of block B is 7.0 ft/sec up the incline. For the instant when the velocity of B is 3.4 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. B 170 Answers: VB/A = ft/sec OB/A = i ft/sec2 VC= i ft/sec
