Three carts of masses m₁ = 4.50 kg, m₂ = 9.00 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 = 3.00 m/s to the left, as shown below. Velcro couplers make the carts stick together after colliding. M₁ 1₂ (a) Find the final velocity of the train of three carts. magnitude m/s direction --Select--- 1/3 (b) Does your answer require that all the carts collide and stick together at the same moment? O Yes O No What if they collide in a different order?
