A car of 1200 kg stays at rest on a horizontal icy rink (no friction at all). David of 60 kg moves at 10 m/s toward the car and collides with the car head-to-head. Just after the collision, David obtains a backward speed of 1.5 m/s away from the car. What is the speed of the car just after the collision, and which direction Does the car go?
