Problem 5.33 The coefficient of kinetic friction between a 50 kg crate and the warehouse floor is 80 % of the corresponding coefficient of static friction. The crate falls off a forklift that is moving at4 m/s and then slides along the warehouse floor for a distance of 3.5 m before coming to rest. Part A What is the coefficient of static friction between the crate and the floor? Express your answer to one significant figure. #PLEASE SHOW WORK
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...

Why is the friction equal to the force? A crate of mass 180 kg sits on a horizontal floor. The coefficient of static friction between the crate and the floor is 0.4, and the coefficient of kinetic friction is 0.36. You push the crate with a horizontal force of 600 N. What is the magnitude of the frictional force on the crate by the floor in this situation? [Use g = 9.81 m/s2] Incorrect 635.69 N. Incorrect 706.32 N Incorrect...
