A bedroom bureau with a mass of 57 kg, including drawers and clothing, rests on the horizontal floor. The coefficient of static friction between the bureau and the floor is 0.45 and nothing except the floor is touching the bureau initially.
(a) What is the static friction force on the bureau initially?
N
