In an isolated system, bicycle 1 and bicycle 2, each with a mass of 30 kg, collide. bicycle 1 was moving to the right at 2 m/s, while bicycle 2 was moving to the left at 4 m/s. what is the magnitude of their combined momentum before the crash?

Which configuration would produce an electric current?

A 1200 kg car is moving at 5.0 m/s east. it strikes an 1800 kg car at rest. the cars have an elastic collision and move in the east or west direction. the velocity of the 1200 kg car after the collision is:
