While ice skating, you un-intentionally crash into a person. Your mass is 60 kg, and you are traveling east at 8.0 m/s with respect to the ice. The mass of the other person is 80 kg, and he is traveling north at 9.0 m/s with respect to the ice. You hang on to each other after the collision.
A. In what direction and at what speed are you traveling just after the collision?
B. What are the momenta of you and the other person before collision?
