Two carts, labeled 1 and 2, are headed toward each other along a level track. Both carts roll without friction and the only significant horizontal forces acting on the carts are the forces that they exert on each other. Cart 1 has a mass of 2.13 kg. Before the collision it was moving to the right with a speed v1j of 1.9 m/s. Cart 2 has a mass of 3.11 kg. Before the collision it was moving to the left with a speed v2 of 1.8 m/s. These two speeds, v1¡ and v2; are measured in the laboratory reference frame (the frame in which the track is not moving). The two carts had a completely elastic collision. Calculate the velocity (in units of meters per second) of cart 1 after the collision, as measured in the laboratory frame. The positive direction points to the right, and the sign (positive or negative) of your answer is important.
