Colliding Cars
5 of 10
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.
I Review | Constants | Periodic Table
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 v, and car 2 was
traveling northward at a speed of v9. (Figure 1)After the
collision, the two cars stick together and travel off in the
direction shown.
Part B
Find the tangent of the angle 0.
Express your answer in terms of the magnitudes of the initial momenta of the two cars, pi
and p2, or the quantities given in the problem introduction.
