Question

how do i solve this problem?

6. (10 pts) You observe a 3 car accident in which everyo userve a 3 car accident in which everyone was safe. Car 1 (1550 kB) Siding on mys on runs into Car 2 (also 1550 kg) car at rest. After the first collision, the car does not move, but Car 2 moves away. The now moving Car 2 runs into the back of a stationary Car 3 (3250 kg) and they stick together. Find the final velocity of Cars 2 and 3 and the work done in the accident. (Ice - Ignore friction.) include a diagram with your answer.
