g = 9.8 N/kg а) Mаss 1 (4.2 kg) аnd mass 2 (3.25 kg) are invоlved in a cоllisiоn. If mass 1 has an initial velocity of 6.2 m/s [north] and mass 2 is initially stationary, how much momentum is in the system before the collision? b) If mass 2 has a velocity of 2.75 m/s [East 20 degrees North] after the collision, and momentum is conserved, what is the velocity of mass 1 after the collision?
