The 75-kg man pushes on the 150-kg crate with a horizontal force F. The coefficients of static and kinetic friction between the crate and the surface are μs = 0.3 and μk = 0.1, and the coefficient of static friction between the man's shoes and the surface is μ′s = 0.8. What is the greatest acceleration the man can give the crate if the man's acceleration is zero at this instant? I keep getting 1.96 but it says answer is...
