Question

Two particles arc seen to collide and move jointly together after the collision. During such a collision for the total system,

(a) both the mechanical energy and the linear momentum are conserved

(b) linear momentum is conserved but not the mechanical energy

(c) neither the mechanical energy nor the linear momentum is conserved

(d) mechanical energy is conserved but not the linear momentum

Answer 1

Correct option (b) linear momentum is conserved but not the mechanical energy

Explanation :

In an inelastic collision, the kinetic energy is not conserved but linear momentum is conserved. In this sort of a collision, there is loss in K.E. of the system..
