Question
A man exerts a horizontal force of 127 N on a crate with a mass of 38.2 kg.
HINT
(a) If the crate 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 crate and the floor? (Assume the crate remains stationary.)

(b) What is the minimum possible value of the coefficient of static friction between the crate and the floor? (Assume the crate remains stationary.)
Expert Solution
Given data:
  • The horizontal force is F=127 N
  • The mass of the crate is m=38.2 kg

Calculating the weight of the crate as follows:

w=mg=38.2×9.8=374.36 N

The normal force on the crate is balanced with the weight of the crate w=N
