Under the action of force P, the constant acceleration of block B is 6.4 ft/sec² up the incline. For the instant when the velocity of B is 2.6 t/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: 15° B
