Question

Which is likely to experience a superelastic collision?1) a falling grenade2) two colliding bicycles3) a falling egg4) a falling water drop

Answer 1

ANSWER

1) a falling grenade

EXPLANATION

A superelastic collision is a collision in which there's more kinetic energy at the final state than in the initial state. Usually explosions fall under the category of superelastic collisions. From these options, we can suppose that a falling grenade is likely to explode, so it is the most likely to experience a superelastic collision.
