7. A 15.0 gm toy car moving to the right at 20.0 cm/s has an elastic head-on collision with a 20.0 gm
toy car moving in the opposite direction at 30.0 cm/s. After colliding, the 15.0 gm car moves with a
velocity of 3.14 cm/s to the left. Find the velocity of the 20.0 gm car after the collision.
A) 12.6 m/s to the right
B) 17.4 m/s to the left
C) 12.6 m/s to the left
D) 17.4 m/s to the right
