Document Summary
Object 1 has a mass m1 and a velocity v 1 = (2. 10m/s )x^. Object 2 has a mass m2 and a velocity v 2= 3. 40m/s )y^. The total momentum of these two objects has a magnitude of. 19. 0kg m/s and points in a direction 69. 0 above the positive x axis: find m1, find m2. Two ice skaters stand at rest in the center of an ice rink. A 95-kg astronaut and a 1300-kg satellite are at rest relative to the space shuttle. The astronaut pushes on the satellite, giving it a speed of 0. 24m/s directly away from the shuttle. A car with a mass of 1050kg and a speed of v1 = 15. 0m/s approaches an intersection, as shown in the figure. A 1280kg minivan traveling at v2 is heading for the same intersection. The car and minivan collide and stick together. The direction of the wreckage after the collision is =
