    Work and energy problem
    A child riding a bicycle has a total mass of 48 kg. The child starts from the top if the hill that is 16.0 my high and 107.0 my long at 16.0 m/s. If the force of friction between the bicycle and the hill is 22.0 N, what is the child's speed at the bottom of the hill? (Assume no air resistance).
