15 points! a freight train is being assembled in a switching yard. car 1 has a mass of 65,000 kg and moves with a velocity of +0.80m/s. car 2 with a mass of 92,000 kg and has a velocity of +1.3m/s overtakes car 1 and couples to it. neglecting friction, calculate the final velocity of the two cars after they become coupled.
solve using conservation of momentum.

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.
