A small 100 g cart is moving at 1.20 m/s on a friction less track when it collides with a larger, 1.00 kg cart at rest. After the collision, the small cart recoils at 0.850 m/s. What is the speed of the large cart after the collision?

momentum is conserved in any straight line, so momentum before equals momentum after. Convert all grams to kilograms.

momentum = mass x velocity

(mv) + (mv) = (mv) + (mv)
(0.1 x 1.2) + (1 x 0) = (0.1 x -0.85) + (1v)

Solve for v. One velocity is negative because the car is moving backwards.

v = 0.205 m/s
