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 Two cars of masses my and me collide at an intersection. Before the collision, car 1 was traveling eastward at a speed of v1, and car 2 was traveling northward at a speed of v. (Figure 1)After the collision, the two cars stick together and travel off in the direction shown.

Question
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 Two cars of masses my and me collide at an intersection. Before the collision, car 1 was traveling eastward at a speed of v1, and car 2 was traveling northward at a speed of v. (Figure 1)After the collision, the two cars stick together and travel off in the direction shown.
Part A
First, find the magnitude of 7, that is, the speed of the two-car unit after the collision.
Express v in terms of mi, m2, and the cars' initial speeds v₁ and v2.
