Asked by Doug
A boy exerts a horizontal force of 111 N on a box with a mass of 32.7 kg.
HINT - (a) Make a free-body diagram and apply the x-component of Newton's second law.
(b) Apply the relationship between static friction and the normal force.
(a)
If the box doesn't move, what's the magnitude of the static friction force (in N)?
(b)
What is the minimum possible value of the coefficient of static friction between the box and the floor? (Assume the box remains stationary.)

(a) > 111 N
(b) m g μ = 111 N ... μ = 111 / (32.7 * 9.81)
(b) m g μ = 111 N ... μ = 111 / (32.7 * 9.81)
