Matt (m= 80 kg) and Trey (m =90 kg) slide across an ice skating rink and collide with each
other. Before the collision, Matt was moving 3 m/s to the east and Trey was moving 2 m/s to
the west. After the collision, Matt is moving 1.5 m/s to the west.
A. What was the total momentum of the system before the collision? B. what is the total momentum of the system after the collision? C. what is treys speed after the collision?
