A4.3-g object moving to the right at 22 cm/s makes an elastic head-on collision with a 8.6-g object that is initially at rest. what is the velocity of the 4.3-g mass after the collision?

The right at +20.0 cm/s makes an elastic head-on collision with a 10.0 g object that makes anelastic head-on collision with a 10.0 g object that is initially at rest.(b) Find the fraction of the initialkinetic energy transferred to the 10.0 g object.of small mass before and after collision; V=velocity of big mass after collision.

Ihope you get it right bro
