A boy in a wheelchair (total mass 47.0kg ) has speed 1.40m/s at the crest of a slope 2.60 m high and 12.4m long. at the bottom of the slope his speed is 6.20 m/s. assume air resistance and rolling resistance can be modeled as a constant friction force of 41.0n . find the work he did in pushing forward on his wheels during the downhill ride.
