Some gliders are launched from the ground by means of a winch, which rapidly reels in a towing cable attached to the glider. What average power must the winch supply in order to accelerate a 174-kg ultra-light glider from rest to 23.0 m/s over a horizontal distance of 50.0 m? Assume that friction and air resistance are negligible, and that the tension in the winch cable is constant.
