As shown in the figure below, cars #1 and #2 are sliding across a horizontal frictionless surface. The cars are equipped with a coupling arrangement similar to the one on railroad cars. Car #1 overtakes car #2 and they have a totally inelastic collision and become coupled together. You know the mass of each car; m, = 14.5 kg and m, = 40.0 kg. In addition, you are provided with the following graph, which shows the momentum of car #1 before, during and after the collision. p (kg . m/s) 100 40 - - - t (s) Determine the velocity (in m/s) of car #2 before the collision. x m/s Enter a number
