If the coefficient of static friction between the crate and the ground in Problem is μs = 0.3, determine the minimum coefficient of static friction between the man’s shoes and the ground so that the man can move the crate.

Problem

The coefficient of static friction between the 150-kg crate and the ground is μs = 0.3, while the coefficient of static friction between the 80-kg man’s shoes and the ground is μ’s = 0.4. Determine if the man can move the crate.
