Problem 3: Two ice skaters are imitially at rest. Skater A has a mass of 80kg and skater B has a mass of 70kg. They push off of each other so that skater A is moving in the negative direction at 4 m/s A. What is the momentum of skater A? B. Using what you know about momentum conservation, what is the momentum of B? Which direction are they traveling in? C. What is the velocity of skater B? Include direction -6.4m's
