Figure 1 The positive direction si Vzi Vzi m2 m1 "The lab frame:" This track is not moving. 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 2.11 kg. Before the collision it was moving to the right with a speed v1¡ of 1.8 m/s. Cart 2 has a mass of 3.33 kg. Before the collision it was moving to the left with a speed v2i of 1.7 m/s. These two speeds, v1j and v2j are measured in the laboratory reference frame (the frame in which the track is not moving). Calculate the velocity (in units of meters per second) of the center of mass of the two cart system. The positive direction points to the right, and the sign (positive or negative) of your answer is important.

Figure 1 The positive direction Vzi V zi m1 m2 "The lab frame:" This track is not moving. 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 2.11 kg. Before the collision it was moving to the right with a speed v1¡ of 1.8 m/s. Cart 2 has a mass of 3.33 kg. Before the collision it was moving to the left with a speed v2i of 1.7 m/s. These two speeds, v1j and v2; are measured in the laboratory reference frame (the frame in which the track is not moving). Calculate the velocity (in units of meters per second) of the center of mass of the two cart system. The positive direction points to the right, and the sign (positive or negative) of your answer is important.
