A skier (with the weight of 920 N) has climbed a 6.0 m high hill and will ski down. He started down the hill with an initial velocity of 2.2 m/s. Being a klutz, he made it down the hill but hit a snow bank at the very bottom. Assume no friction and calculate: a) the skier’s velocity at the bottom of the hill as he impacts and b) the average force the snowdrift puts on him if he came to a complete stop in 90 cm
