In the railroad freight yard, an empty freight car of mass m rolls along a straight level track at 1.20 m/s and collides with an initially stationary, fully loaded boxcar of mass 5.80m. The two cars couple together on collision. a.)What is the speed of the two cars after the collision? b.)Suppose instead that the two cars are at rest after the collision. With what speed was the loaded boxcar moving before the collision if the empty one was moving at 1.20 m/s?

A small car of mass 1200 kg traveling east at 60 km/hr collides at an intersection with a truck of mass 3000 kg that is traveling due north at 40 km/hr. The two vehicles are locked together. What is the velocity of the combined wreckage? m₂ = 1200 kg m, - 3000 kg Vo
1.) A car (mass=400 kg) is traveling down a country road (speed is 10 m/s) when it collides with a deer (mass=200 kg) which is running in the opposite direction (speed is 2 m/s). The collision results in the deer getting stuck on the windshield. Treat this collision using the 'conservation of momentum' principle: a) Draw a sketch - label each MASS and each VELOCITY (with arrows for direction). b) Calculate the final speed of the car (remember the deer is stuck on top of the car) after collision (Note: they stick together to form a single mass)
