Question: A 10.0g 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. (Since the collision is head-on, all the motion is along a line.)
- Find the magnitude of the velocity of 30.0 g marble after the collision.
- Find the magnitude of the velocity of 10.0 g marble after the collision.
- Calculate the change in momentum (that is, the momentum after the collision minus the momentum before the collision) for 30.0 g marble.
- Calculate the change in momentum for 10.0 g marble.
- Calculate the change in kinetic energy (that is, the kinetic energy after the collision minus the kinetic energy before the collision) for 30.0 g marble.
- Calculate the change in kinetic energy for 10.0 g marble.
