Three carts of masses m, = 4.50 kg, m2 = 8.50 kg, and mg = 3.00 kg move on a frictionless, horizontal track with speeds of v = 4.00 m/s to the right, v2 = 3.00 m/s to the right, and va = 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 -Select-- (b) Does your answer require that all the carts collide and stick together at the same moment? Yes No What if they collide in a different order? This answer has not been graded yet. Need Help?
