The three air carts shown in the figure have masses, readingfromleft to right, of 4m,2m , and 0m , respectively. The mostmassive cart has aninitial speed of V ; the other two carts are atrest initially.All carts are equipped with spring bumpers that giveelasticcollisions.
a) Find the finalspeed of each cart
b) Verify that thefinal kinetic energy of the system is equal tothe initial kineticenergy. (Assume that the air track is longenoughto accommodate all collisions).
