Three air carts have masses, 4m,2m and m. the most massive cart hasan initial speed of Vo; the other two carts are at restinitially. All carts are equipped with spring bumpers that giveelastic collisions.
a) find the final speed of each cartb) verify that the final kinetic energy of the system is equalto the initial kinetic energy. (assume the air track is long enoughto accommodate all collisions)
