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 165 NN directed 26 degrees below the horizontal. While you slide the chair a distance of 4.70 mm , the chair's speed changes from 1.50 m/sm/s to 2.60 m/sm/s . Find the work done by friction on the chair.

A student pushes a chair of a mass 26.7 kg on a flat surface with no elevation changes at a speed of 10.2 m/s without any acceleration. The coefficient of kinetic friction between the chair's roller and the flat surface is 0.29. What horizontal force (in newtons) does the student applies on the chair to keep it in motion?
