Aboxcar of length 8.3 and height 2.4 is at rest on frictionless rails. inside the boxcar (whose mass when empty is 3500 ) a tank containing 2600 of water is located at the left end. the tank is 1.0 long and 2.4 tall. at some point the walls of the tank start to leak, and the water fills the floor of the boxcar uniformly. assume that all the water stays in the boxcar. after all the water has leaked out what will be the final velocity of the boxcar? (take movement to the right as positive
