A 500-kg cannon and a supply of 59 cannon balls, each with a mass of 19.0 kg, are inside a sealed railroad car with a mass of 50000 kg and a length of 41 m. The cannon fires to the right; the car recoils to the left. The cannon balls remain in the car after hitting the wall. After all the cannon balls have been fired, what is the greatest distance the car can have moved from its original position?What is the speed of the car after all the cannon balls have come to rest on the right side?
xcm= (m1x1 + m2x2) / (m1+m2)
I tried to solve for the left part of the equation and then the right but I don't know how to set it up, please help!
