You Push Horizontally on a 120-N Box That Is Initially

Short Answer

You push horizontally on a 120-N box that is initially resting on a horizontal table.The coefficient of static friction between the box and the table is 0.75,and the coefficient of kinetic friction is 0.40.Find the friction force exerted on the box by the table if the push is equal to (a)84 N; (b)94 N.
