to the right. What is the wolf's momentum?
The elk has a mass of 180 kg. What does the elk's speed have to be for it to have the same momentum as the
wolf?

Which best represents the law of conservation of mass ?

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?
