Mass 10 kg runner with speed 10 m/sec. Access to 2 kg mass being bumped wong in front with 4 meters/second. In the same direction If the collision is a collision completely flexible. You shall find that the collision and then each cube object contains the speed?
A mass of 10 kg at a speed of 10 m / sec to the mass of 2 kg being swung forward at a speed of 4 m / sec in the same direction. If a collision is perfectly elastic collision. Now what is now the object each core will have much speed.
Mass 10 kg, running at a speed of 10 meters / seconds into the mass 2 kg is that existence forward speeds 4 meters / sec. In the same direction. If this is a flexible collision bump completely.
