8.48 • A 10.0 g marble slides
to the left at a speed of 0.400 m/s
on the frictionless, horizontal
surface of an icy New York side-
walk and has a head-on, elastic
collision with a larger 30.0 g
marble sliding to the right at a
speed of 0.200 m/s (Fig. E8.48).
(a) Find the velocity of each
marble (magnitude and direction) after the collision. (Since the collision
is head-on, all motion is along a line.) (b) Calculate the change in mo-
mentum (the momentum after the collision minus the momentum before
the collision) for each marble. Compare your values for each marble.
