A 10.0 g marble slides to the left with a velocity of magnitude 0.400 m/sm/s on the frictionless, horizontal surface of an icy New York sidewalk and has a head-on, elastic collision with a larger 30.0 gg marble sliding to the right with a velocity of magnitude 0.200 m/sm/s. Let +x+x be to the right. (Since the collision is head-on, all the motion is along a line.) What's the answer for all the parts A, B, C, D, E, G, H?
