For an inelastic collision between two spherical rigid bodies:

1. The total kinetic energy is conserved
2. The linear momentum is not conserved
3. The total mechanical energy is not conserved
4. The linear momentum is conserved

Correct answer: The linear momentum is conserved

Solution

In an inelastic collision, kinetic energy is not conserved because some of it is transformed into heat, sound, or deformation. However, linear momentum of the system remains conserved if external forces are negligible.
