Two particles of mass m1 = 2.0 kg and m2 = 2.6 kg undergo a one-dimensional head-on collision as shown in the figure below. Their initial velocities along x are v1i = 10 m/s and v2i = -7.3 m/s. The two particles stick together after the collision (a completely inelastic collision). (Assume to the right as the positive direction.)

Consider the collision between two hockey pucks in the figure below. They do not stick together. Their speeds before the collision are v1i = 29 m/s and v2i = 11 m/s. It is found that after the collision one of the pucks is moving along x with a speed of 4 m/s. What is the final velocity of the other puck?

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 m1 and m2 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 v2. (Figure 1) After the collision, the two cars stick together and travel off in the direction shown.

Part A
First, find the magnitude of Vector V, that is, the speed little v of the two-car unit after the collision. Express little v in terms of m1, m2, and the cars’ initial speeds v1 and v2.

Part B
Find the tangent of the angle theta. Express your answer in terms of the momenta of the two cars, p1 and p2.

Part C
Suppose that after the collision, tan=1; in other words, theta is 45 degrees. This means that before the collision:Choose
one:

  • The magnitudes of the momenta of the cars were equal.
  • The masses of the cars were equal.
  • The velocities of the cars were equal.

 

A car with mass 1.45*10^3 kg traveling east at a speed of 24.4 m/s collides at an intersection with a 2.49*10^33 kg van traveling north at a speed of 19.2 m/s, as shown in the figure. Find the magnitude and direction of the velocity of the wreckage after the collision, assuming that the vehicles undergo a perfectly inelastic collision (that is, they stick together) and assuming that friction between the vehicles and the road can be neglected.
