You slide a chair across a rough, horizontal surface. The chair's mass is 18.8 kg. The force you exert on the chair is 156 N directed 26 degrees below the horizontal. While you slide the chair a distance of 5.00 m , the chair's speed changes from 1.30 m/s to 3.10 m/s . Find the work done by friction on the chair.
