Unformatted text preview: 3. Consider three masses, m 1 = 1kg, m 2 = 2kg , and m 3 = 3kg. At t = 0 , m 1 is at the point (x, y) = (3m, 0) and has a velocity of 2m/s x , m 2 is at the point (x, y) = (0, 2m) and has a velocity 1m/s y , and m 3 is at the point (x, y) = (2m, 0) and has a velocity of 3m/s y . You may answer these with the components of the vectors. a) What is the total momentum of the system? b) What is the velocity of the center of mass? c) What is the initial location of the center of mass? d) Find the location of the masses at t = 1sec and recalculate the position of the center of mass using those new locations. e) Using your answers from parts c) and d), show that the velocity of the center of mass is the same as what you got from part b)....
