If the collision is elastic, the total kinetic energy of the system is constant.
Regardless of the type of collision, the total momentum of the system is always
conserved.
In a perfectly inelastic collision both the kinetic energy and the momentum of the
system is conserved.
If the collision is elastic, the kinetic energy of each ball remains constant.
If the collision is inelastic, the total kinetic energy of the system is not conserved.
If the collision is inelastic, the momentum of the system is not conserved.
The two objects will not collide if the momentum of ball 2 is greater than the
momentum of ball 1.
The momentum of each ball is always constant.
Two identical freight cars roll without friction towards each other, in opposite directions, on a level track. One car rolls at 3.4 m/s. After the cars collide, they couple and roll together with a speed of 2.2 m/s. The speed of the second car before the collision is _______ m/s (to two significant figures).
