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 I'D-Us with a velocity of magnitude 0.200 m/s.
(a) Find the velocity of each marble (magnitude and direction) after the collision.
(b) Calculate the change in momentum for each marble. Compare the values.
(c) Calculate the change in kinetic energy for each marble. Compare the values.
