Question

A 26.2 g marble sliding to the right at 62.0 cm/s overtakes and collides elastically with a 13.1 g marble moving in the same direction at 15.5 cm/s. After the collision, the 13.1 g marble moves to the right at 77.5 cm/s. Find the velocity of the 26.2 g marble after the collision.

Answer 1

I think you can do this with just the momentum equation
26.2*62+13.1*15.5=13.1*77.5+26.2*V

solve for V

Answer 2
