In this problem we will consider the collision of two cars initially moving at right angles. We assume that after the collision the cars stick together and travel off as a single unit. The collision is therefore completely inelastic. First, find the magnitude of , that is, the speed w of the two-car unit after the collision. The two cars shown in the figure, of masses my and ma. collide at an Express u in terms of m1, #2, and the cars' initial speeds , and "2. intersection. Before the collision, car 1 was traveling eastward at a speed of 1. and car 2 was traveling northward at a speed of u2.
