Question

In an inelastic collision between two particles

which of the following is true?
1. Energy and momentum are conserved
while the particles’ shapes are distorted.
2. None of these is true.
3. Mechanical energy is conserved but the
total momentum is not.
4. The colliding particles always shatter.
5. Neither mechanical energy nor momentum is conserved.

Answer 1

(2) None of these is true

Momentum is conserved, energy is not (some goes to deformation, etc.)
