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 on the box if the push is equal to (a) 84 N; (b)
94 N.
