A 24.9 g marble sliding to the right at 22.0

cm/s overtakes and collides elastically with a
13.2 g marble moving in the same direction
at 11.8 cm/s. After the collision, the 13.2 g
marble moves to the right at 25.0 cm/s.
Find the velocity of the 24.9 g marble after
the collision.
Answer in units of cm/s.

M1*V1 + M2*V2 = M1*V + M2*25.
24.9*22 + 13.2*11.8 = 24.9V + 13.2*25.
V = ?
