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?
