Question

Two spheres, each of mass m and velocity v are involved in a perfectly inelastic head-on collision. The percentage loss in Kinetic energy due to the collision is

Answer 1

Answer:

100 %

Explanation:

In "perfectly" inelastic collision,two bodies stick together ( like an accident between two cars). So they will be unable to move. In this case they will lose all of their kinetic energy coz they are motionless after collision ( e.g., accident in case of cars).
