A 10.0-g marble slides to the left with a velocity of magnitude 0.400 m/s on the frictionless, horizontal surface of an icy New York sidewalk and has a head-on, elastic collision with a larger 30.0-g marble sliding to the right with a velocity of magnitude 0.200 m/s. Let +x be to the right.
a)Calculate the change in kinetic energy (that is, kinetic energy after the collision minus the kinetic energy before collision) for each marble. Compare the values you get for each marble.
1 answer
Elastic collision assumes no energy lost. If energy is lost you need to know something about the situation after the collision.
