1. while skiing, sam flies down a hill and hits a jump. he has a mass of 75 kg, and he leaves the jump at 18 m/s. what is his momentum as he leaves the jump?
2. how fast would a 0.25 kg football have to be traveling to have the same momentum as a 0.05 kg bullet travelling 500 m/s?
3. sarah, who has a mass of 55 kg, is riding in a car at 20 m/s. she sees a cat crossing the street and slams on the brakes! her seat-belt stops her from flying forward, bringing her to rest in 0.5 seconds. how much force did the seat-belt put on sarah?

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
