A heavy semi-truck collides head-on with a small, light car. Before the collision the vehicles were moving with the same speed but in opposite direction.

A. Just before the collision, was the magnitude of the momentum of the car greater, equal or less than that of the truck?

B. Just before the collision, was the kinetic energy of the car greater, equal or less than that of the truck?

C. During the collision, is the force that the car exerts on the truck greater, equal or less than the force that the truck exerts on the car?

D. During the collision, is the magnitude of the acceleration of the car greater, equal or less than the magnitude of the acceleration of the truck?

E. If the two vehicles stick together immediately after the collision, which way will they be moving, if at all?

Most of us know intuitively that in a head-on collision between a large dump truck and a subcompact car, you are better off being in the truck than in the car. Why is this? Many people imagine that the collision force exerted on the car is much greater than that exerted on the truck. To substantiate this view, they point out that the car is crushed, whereas the truck is only dented. This idea of unequal forces, of course, is...

A car of mass 2400 kg collides with a truck of mass 4500 kg, and just after the collision the car and truck slide along, stuck together, with no rotation. The car's velocity just before the collision was <35, 0, 0> m/s, and the truck's velocity just before the collision was <-10, 0, 21> m/s. What is the increase in internal energy of the car and truck (thermal energy and deformation)?

As shown below, a 840 kg car traveling east collides with a 1730 kg pickup truck that is traveling north. The two vehicles stick together as a result of the collision. After the collision, the wreckage is sliding at vf = 19 m/s in the direction θ = 25° east of north. Calculate the speed of each vehicle before the collision. The collision occurs during a heavy rainstorm so you can ignore friction forces between the vehicles and the wet...
