3. Two marbles (m = 0.050 kg each) moving on a table TOWARDS each other with the speed of 0.3 m/s collide, and start moving away from each other. a) What is the total momentum of this system before the collision? V = P1 = Ptatal m/s, V = kg m/s, p2 = kg m/s m/s, kg m/s, b) Determine the magnitude and direction of the velocity of each marble and the total linear momentum after the head-on elastic collision (hint: you may use the Collision lab to model this event. The initial POSITIONS of the balls don't matter as long as they are some distance apart). V = p1 = Ptotal = m/s, V2 = m/s, kg m/s, P2 kg m/s = kg m/s,
