A 24.0 g marble sliding to the right at 60.8 cm/s overtakes and collides elastically with a 12.0 g marble moving in the same direction at 15.2 cm/s. After the collision, the 12.0 g marble moves to the right at 76 cm/s. Find the velocity of the 24.0 g marble after the collision.

Answer 1

M1*V1 + M2*V2 = M1*V + M2*0.76
24*60.8 + 12*15.2 = 24*V + 12*0.76. Solve for V(cm/s).
