The uniform crate has a mass of 220 kg . The coefficient of static friction between the crate and the floor is ?s = 0.2. The coefficient of static friction between the man's shoes and the floor is ??s = 0.45. Assume the man exerts only a horizontal force on the crate.

 

 

Problem 8.50 The uniform crate has a mass of 220 kg. The coefficient of static friction between the crate and the floor is 0.2. The coefficient of static friction between the man's shoes and the floor is s = 0.45. Assume the man exerts only a horizontal force on the crate. (Figure 1) Part A Determine the smallest mass of the man so he can move the crate.
