Part A An air-track cart with mass m = 0.25 kg and speed vo = 1.5 m/s approaches two other carts that are at rest and have masses 2m and 3m, as indicated in (Figure 1). The carts have bumpers that make all the collisions elastic. Find the final speed of cart 1, assuming the air track extends indefinitely in either direction. Express your answer to two significant figures and include appropriate units.
