A 26.3 g marble sliding to the right at 21.0 cm/s overtakes and collides elastically with a

13.3 g marble moving in the same direction at 12.2 cm/s. After the collision, the 13.3 g marble moves to the right at 23.7 cm/s.
Find the velocity of the 26.3 g marble after the collision.
Answer in units of cm/s

1 answer

Conservation of momentum
Intial momentum=final momentum
26.3*21+13.3*12.2=13.3*23.7+26.2V
solve for V
