The uniform crate has a mass of 140 kg kg . The coefficient of static friction between the crate and the floor is μ s μs = 0.2. The coefficient of static friction between the man's shoes and the floor is μ ′ s μs′ = 0.45. Assume the man exerts only a horizontal force on the crate. Determine the smallest mass of the man so he can move the crate.
