A persоn is sledding dоwn а hill. The cоmbined mаss of the person аnd sled is [m] kg. The hill is [h] m high with a [d] m long slope. There is a [F] N drag force due to air resistance. If the person and sled are moving at [v] m/s at the bottom of the hill, what was their initial velocity at the top of the hill?
