We assume that after the collision the cars stick together and travel off as a single unit. The collision is therefore completely inelastic. The two cars shown in the figure, of masses and , collide at an intersection. Before the collision, car 1 was traveling eastward at a speed of , and car 2 was traveling northward at a speed of . After the collision, the two cars stick together and travel off in the direction shown. Part A First, find the magnitude of , that is, the speed of the two-car unit after the collision. Hint A.1 Conservation of momentum Hint not displayed Hint A.2 Determine the x and y components of momentum Hint not displayed Hint A.3 A vector and its components Hint not displayed Hint A.4
