A building under construction requires building materials to be raised to the upper floors by cranes or elevators. A quantity of cement is lifted 76.2 m by a crane, which exerts a force on the cement that is slightly larger than the weight of the cement. If the work done in excess of the work done against gravity is 1.31 x 10 3J, what is the unbalanced, overall force exerted on the cement?
