A fast moving truck loses momentum equal to 2 kg m s-1 after colliding with a stationary car. Will the car lose or gain momentum ? How much momentum is lost or gained by the car if the truck comes to the rest after collision ?

Step 1
According to this principle, the total momentum of an isolated system remains constant if no external forces act on it. This means that the momentum lost by one object in the system must be gained by another object in the system. In this case, the truck and the Show more…

A car with a mass of 1200 kg and traveling 40 m/s east runs into the back of a parked truck with a mass of 2000 kg. After the collision the car and truck do not stick together, but the car is stopped. If momentum is conserved, what would the velocity of the truck be after the collision?

1) A 4,600 kg truck runs into the rear of a 1,000 kg car that was stationary. The truck and car are locked together after the collision and move with speed 2 m/s. Compute how much kinetic energy was "lost" in this inelastic collision.
