A 15.0-kg wagon with wheels that turn with negligible friction travels to the right at 5.0 m/s on a horizontal surface with negligible friction as shown in the diagram. When the wagon reaches Point A, a 5.0-kg mass is placed upon the wagon. V = 5.0 m/s 5.0 kg (a) Determine the magnitude of the momentum of the wagon before the mass is placed upon it. (b) Determine the speed of the wagon after the mass is placed upon it. (c) Consider the kinetic energy changes in an inelastic collision, specifically whether the initial values of one of the physical quantities affect the fraction of mechanical energy dissipated in the collision. How could you modify this experiment to investigate this question? Be sure to explicitly describe the calculations you would make, specifying all equations you would use. (Do not actually do any algebra or arithmetic.)
