Cassy shoots a large marble (Marble A, mass: 0.06 kg) at a smaller marble (Marble B, mass: 0.03 kg) that is sitting still. Marble A was initially moving
at a velocity of 0.7 m/s, but after the collision it has velocity of -0.2 m/s.
What is the resulting velocity of marble B after the collision? Be sure to
show your work for solving this problem along with the final answer.7 (5
