An air-track cart with mass m=0.20kg and speed v0=1.5m/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.

Question

An air-track cart with mass m=0.20kg and speed v0=1.5m/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.

Find the final speed of cart 2, assuming the air track extends indefinitely in either direction.

Find the final speed of cart 3, assuming the air track extends indefinitely in either direction.
