Chapter 2, Problem 2.4P
An automobile weighing 2000 kg and going at a speed of 60 km/h collides with a truck weighing 5 metric tons that was moving perpendicular to the direction of the automobile at a speed of 4 km/h. If the two vehicles become joined in the collision, what is the magnitude and direction of their velocity relative to the automobile's original direction?

Two vehicles A and B are traveling west and south, respectively, toward the same intersection where they collide and lock together. Before the collision, A (total mass 1250 kg) is moving with a speed of 64 km/hr and B (total mass 1650 kg) has a speed of 96 km/hr. Find the speed and direction of vehicles immediately after the collision
In a physics lab, a 0.5 kg cart moving at 0.5 m/s collides with a second cart which is initially at rest. The two carts move off together with a speed of 0.3 m/s after the collision. Determine the mass of the second cart.
Three identical cars are being unloaded from an automobile carrier. Cars B and C have just been unloaded and are at rest with their brakes off when car A leaves the unloading ramp with a velocity of 5.76 ft/s and hits car B , which hits car C. Car A then again hits car B . Knowing that the velocity of car B is 5.04 ft/s after the first collision, 0.630 ft/s after the second collision, and 0.709 ft/s after the third collision, determine (a) the final velocities of cars A and C, (b) the coefficient of restitution for each of the collisions.
