A moving company is called into a building and asked to relocate 520 bricks to a location 15 meters above the ground. If each brick is 4 kilograms, the amount of work needed to accomplish the task is: 305,760 J. Work to lift 1 brick: W = mgh = (4 kg)(9.8 m/s²)(15 m) = 588 J Work to lift 520 bricks: W = 520(588 J) = 305,760 J.
