A truck and a car collide into each other. The car has a mass of 845kg and is moving at 15m/s. The truck is moving at 10m/s in the opposite direction with a mass of 1500kg. What is the total momentum after the two vehicles collide? SHOW ALL WORK!

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.

Mutt and jeff are running along a path each pushing a cart loaded with rocks. if mutt's wagon has a mass two times greater than jeff's and they want to stay together, arriving at their destination at the same time, what must happen? a) jeff should slow down so mutt can catch up. b) mutt must use half as much force to push his cart. c) mutt must use twice as much force to push his cart. d) mutt and jeff will use the same force, but mutt will take bigger steps.
