A Girl is pushing on a 45 kg dresser with 300 N of force. The dresser has a coeficient of statice friction of 0.83 and a coeficient of kinetic friction of 0.55.
Does the dresser move?
What quantitative evidence can you give to prove that this?
How much is the force of friction on the dresser?
How much will the friction be if her brother puts a 15 kg dictionary on top of the dresses?
