Three carts of masses m1 = 4.50 kg, m2 = 7.50 kg, and m3 = 3.00 kg move on a frictionless, horizontal track with speeds of v1 = 4.00 m/s to the right, v2 = 3.00 m/s to the right, and v3 = 3.50 m/s to the left, as shown below. Velcro couplers make the carts stick together after colliding. (a) Find the final velocity of the train of three carts. magnitude m/s direction right or left (b) Does your answer require that all the carts collide and stick together at the same moment? Yes or No?  Explain What if they collide in a different order?
