The 300-kg bar B, originally at rest, is being towed over a series of small
rollers. Determine the force in the cable when t = 5s, if the motor M is
drawing in the cable for a short time at a rate of v = (0.47²) m/s, where t is in
seconds (0 <= t<= 6 s). How far does the bar move in 5s? Neglect the mass
of the cable, pulley, and the rollers.
