Some gliders are launched from the ground by means of a winch, which rapidly reels in a towing cable attached to the glider. Find what average power must the winch supply in order to accelerate a 180 kilogram ultra-light glider from rest to 25.0 m/s over a horizontal distance of 52.0 meter? Suppose that friction and air resistance are negligible, and that the tension in the winch cable is constant. Answer must be in watts.
