QI-A 75-Kg man wants to pull a 145- Kg box and the coefficient of static friction between the box and the ground is μ = 0.3, while the coefficient of static friction between the man's shoes and the ground is μ = 0.4. Determine the following: 1- If the man can move the crate, and the tension force is in the cable. 2- The minimum coefficient of static friction is between the man's shoes and the ground, so that the man can move the crate. ka 20
