A strong man rolls a heavy stone ball up a vertical column at a constant speed. The ball has a mass of 100 kg. He pushes it with a force of 1132 N at an angle of 30 degrees from the vertical (upwards and into the column). The components of this force are 980 N upward (vertical) and 566 N into the column (horizontal). If he rolls the ball a vertical distance of 1.5 m in 2 seconds. How much work does he do?

work = force * distance = 980*1.5 J
