The 80 kg man pushes on the 120 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 uk = 0.2. The coefficients of static and kinetic friction between the man's and the surface are μs = 0.8 and µk = 0.5. a) Calculate the normal force generated by the surface on the man and the crate. b) Using the information from part a), prove that the man will be able to move the crate c) What is the greatest acceleration the man can give the crate?
