A worker wants to turn over a uniform 1220-N rectangular crate by pulling at 53.0 ? on one of its vertical sides (the figure (Figure 1) ). The floor is rough enough to prevent the crate from slipping.
A: What pull is needed to just start the crate to tip?
B: How hard does the floor push on the crate?
C: Find the friction force on the crate.
D: What is the minimum coefficient of static friction needed to prevent the crate from slipping on the floor?

You have a crate full of books with a total mass of 32 kg that you have to move from your bedroom to the door of your apartment using a rope attached to the crate. The coefficient of static friction between the crate and the floor is 0.65, and the coefficient of kinetic friction is 0.45 (a) Pulling the rope horizontally, what is the minimum force you have to pull with to get the crate to start moving? (b) Once...

You are a fitness trainer developing an exercise that involves pulling a heavy crate across a rough surface. You attach a rope to a crate of mass M = 45.0 kg and place it on a carpeted track. Using your physics expertise, you have already determined that the coefficient of kinetic friction between the crate and the carpet is μk = 0.430. To test the apparatus, you have one of your employees pull on the rope as hard as she...
A warehouse worker is pushing a 90.0 kg crate with a horizontal force of 276 N
A warehouse worker is pushing a 90.0 kg crate with a horizontal force of 276 N at a speed of v = 0.865 m/s across the warehouse floor. He encounters 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 floor. (b) Determine the net...

1. You want to move a 500-N crate across a level floor. To start the crate moving, you have to pull with a 230-N horizontal force. Once the crate breaks loose and starts to move, you can keep it moving at constant velocity with only 200 N. What are the coefficients of static and kinetic friction? 2. In the previous example, suppose you move the crate by pulling upward on the rope at an angle of 30.0◦ above the horizontal....
