Marble C, with mass 5. 0 g, moves at a speed of
20. 0 cm/s. It collides with a second marble, D, with mass
10. 0 g, moving at 10. 0 cm/s in the same direction. After
the collision, marble C continues with a speed of
8. 0 cm/s in the same direction.
a. Sketch the situation, and identify the system. Identify
the before and after situations, and set up a coordi-
nate system.
b. Calculate the marbles' momentums before the
collision.
c. Calculate the momentum of marble C after the
collision.
d. Calculate the momentum of marble D after the
collision.
What is the speed of marble D after the collision?
