The driver of a 3000 lb car, coasting down a hill, sees a red light at the bottom, and must stop. His speed when he applies the brakes is 60mph, and he is 100feet (vertically) above the bottom of the hill.

a) How much energy must dissipated as heat if we neglect wind resistance and other frictional effects?

b) What quantity of water could be heated to boiling with this energy?
