The total momentum before the collision is 40000 kgm/s left. Both vehicles move with a velocity of 5 m/s left after the collision. If external forces can be ignored, then what is the mass of the car? 5. Two skaters with masses of 40 kg and 50 kg are at rest on frictionless ice. The 40 kg skater pushes the 50 kg skater. After the push, the 50 kg skater moves right at 4 m/s. What is the 40 kg skater's velocity after the push? 6. A 2500 kg truck moving right at 15 m/s collides and sticks to a 1500 kg car moving right at 10 m/s. If external forces can be ignored, then what are the vehicles' velocities after the collision? What are the impulses on the vehicles?
