You’re sanding a table. You must exert a force of 23 N on the sandpaper to keep it moving steadily across the table’s surface. You slide the paper back and forth for 23 minutes, during which time you move it 1090 m. How much work have you done?

    Force x (total distance moved, in either direction)
    = 23 * 1090 = ___ joules

    It doesn't matter how long it took.
