C. If the mass of each car is 7000kg and the final velocity of the trains after collision is 2m/s. Then solve the equation described above.
D. Solve the equation described in part b with the same data as in part C if the mobile train car was moving at 28m/s before collision and continues on after collision at 7m/s. What is the kinetic energy before collision and After collision? Is it conserved?
