12 of 14 > Review | Constants | Periodic Table 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. The two cars shown in the figure, of masses m and m2, collide at an intersection. Before the collision, car 1 was traveling eastward at a speed of 21, and car 2 was traveling northward at a speed of 12. (Figure 1)After the collision, the two cars stick together and travel off in the direction shown. Find the tangent of the angle 0. Express your answer in terms of the magnitudes of the initial momenta of the two cars, P1 and p2, or the quantities given in the problem introduction. View Available Hint(s) VO ?
