Two cars of equal mass are traveling as shown in the figure below just before undergoing a collision. Before the collision, one of the cars has a speed of 17 m/s along +x, and the other has a speed of 29 m/s along +y. The cars lock bumpers and then slide away together after the collision. What are the magnitude and direction of their final velocity?

Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1300 kg and was approaching at 5.00 m/s due south. The second car has a mass of 900 kg and was approaching at 23.0 m/s due west. (a) Calculate the final velocity (magnitude in m/s and direction in degrees counterclockwise from the west) of the cars. (Note that since both cars have an initial velocity, you cannot use the equations for conservation...

Ball A has a mass of 100 kg; it is traveling to the right at 6.2 m/s. Ball B has a mass of 120 kg; it is traveling to the left at 4.7 m/s.(a) Assume an inelastic collision (they stick together). Determine velocity at which the two move off together. Give speed and direction. Pay attention to the + and – signs.(b) Assume they have a perfectly elastic collision. Determine the speeds and directions of each of the balls.

Two cars collided at an intersection. Their frames became enmeshed and then they moved together as one object. As an accident investigator on the scene, you were able to determine that car A, of mass 1900 kg, was initially traveling eastwards. You found that car B, of mass 1700 kg, had an onboard computer that registered its southwards velocity of 20 m/s. The tire skid marks on the pavement show that they both moved −25° south of east. You are...
