A 1200kg car traveling initially at v initial of 25m/s in aneasterly direction crashes into the back of a 9000kg truck movingin the same direction at v truck of 20 m/s. The velocity of the carimmediately after the collision is 18 m/s in the eastdirection.a) What is the velocity of the truck immediately after thecollision?b) What is the change in mechanical energy of the car-trucksystem in the collision?c) Account for this change in mechanical energy.
