question 6

5. A particle moving with kinetic energy =3J makes an elastic head-on collision with a stationary particle which has twice its mass during the impact.

(A) the minimum kinetic energy potential of the system is 1J.
(B)the maximum elastic potential energy of the system is 2J.
(C)momentum and total energy are conserved at every instant.
(D)the ratio of kinetic energy to potential energy of the system first decreases and then increases.

Answer 1

(B)the maximum elastic potential energy of the system is 2J.
