Two carts roll on a level track, with negligible friction. These carts have small magnets at their ends, so that when they collide, they stick together. The first cart has a mass of 675 grams and is rolling at 0.75 m/s to the right; the second has a mass of 500 grams and is rolling at 1.5 m/s, also to the right. After the collision, what is the velocity of the two joined carts?
