How much force will it take to accelerate a 900-kg car at 6 m/s^2

To assist with a class demonstration, a student (whose mass is 60 kg) filled a water balloon with 2 kg of water. He then climbed to the second floor (10 metres) of the school and held the balloon out of a window. How much work did the student do?
