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...

A warehouse worker is pushing a 90.0 kg crate with a horizontal force of 288 N at a speed of v = 0.850 m/s across the warehouse floor. He encounters a rough horizontal section of the floor that is 0.75 m long and where the coefficient of kinetic friction between the crate and floor is 0.357. (a) Determine the magnitude and direction of the net force acting on the crate while it is pushed over the rough section of the...

1. You have one last large 50 kg crate to move from your apt to your car and your inconsiderate roommate took the cart with him. So in order to move the crate, you tie a string to it and pull at an angle of 30° above the horizontal such that you move the crate along at a relatively constant speed. The coefficient of kinetic friction between the floor and the crate is 0.2 and the coefficient of static friction...

Two laborers are controlling the slide of a 400 kg crate down a ramp at constant velocity. One of them is pulling a rope (T) and the other is holding (resisting) by hand (P). The angle of contact each makes with the crate is 30.0 degree. Draw a free-body diagram for the crate and identify all forces. (2 pts.) If the coefficient of kinetic friction between the crate and the ramp is 0.20, the ramp angle is 25.0 degree, and...
