To speed up the unrolling of a telephone cable the trailer with the reel of cable starts from rest and is given an initial acceleration of 3 ft/sec2Simultaneously, the tow truck pulls the free end of the cable horizontally in the opposite direction with an initial acceleration of 2 ft/sec2Â If both vehicles start from rest at the same instant, determine the magnitude of the total acceleration of point A on the forward end of the horizontal reel diameter (a) just as the motion starts and (b) one second after the start of the motion.
