Under the action of force P, the constant acceleration of block B is 5.1 ft/sec² 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. Answers: VB/A = AB/A VC= 15° i i i B ft/sec ft/sec² ft/sec
