II. Two adults push on a 60−kg crate (no friction between the crate and floor). They wish to push the crate straight along the x -axis as shown. a. With what minimum force must the third person push to keep the crate going along the x -axis? b. What would be the crate's acceleration given the third force from part (a)?

A 33.0 kg crate of tools rests on a horizontal floor. You exert a gradually increasing horizontal push on it, and the crate just begins to move when your force exceeds 313 N. Then you must reduce your push to 208 N. to keep it moving at a steady 25.0 cm/s. Part A What are the coefficient of static and kinetic friction between the crate and the floor? Enter your answers numerically separated by a comma. Submit Request Answer Part B What push must you exert to give it an acceleration of 1.10 m/s2 ? Express your answer with the appropriate units. Part C Suppose you were performing the same experiment on this crate but were doing it on the moon instead, where the acceleration due to gravity is 1.62 m/s2. What magnitude push would cause it to move? Express your answer with the appropriate units. Submit Request Answer Part D What would its acceleration be if you maintained the push in part B ? Express your answer with the appropriate units.A 33.0 kg crate of tools rests on a horizontal floor.

Learning Goal: Static and Kinetic Friction Short Calclations A 25.0 kg wooden crate rests on a wood floor. The coefficient of static friction between the wood crate and the wood floor is μs = 0.53. The coefficient of kinetic friction between the wood crate and the wood floor is 0.44. You pull on the rope attached to the crate. The magnitude of the gravitational acceleration is 9.80 m/s2. Part A - What maximum force (in Newtons) can you exert horizontally on the crate without moving it? Part B - If you pull on the crate with a 38.96 N horizontal force, what is the magnitude of the frictional force? Part C - Now you increase the pulling force gradually to the value in Part A, the crate will start moving. Notice that the type of frictional force will change and the magnitude will also change. After the crate starts moving, your pulfing force remains at the value in Part A. What will be the crate's acceleration? As shown in the same crate from the above parts rests on the same wooden floor. A 100 N force presses on the crate from above. Part D - What is the magnitude of the normal force on the crate by the floor? Part E - What is the minimum horizontal pulling force (in Newtons) to make the crate start moving?

A book of mass M is positioned against a vertical wall. The coefficient of friction between the book and the wall is μ. You wish to keep the book from falling by pushing on it with a force F applied at an angle θ with respect to the horizontal (−π/2 < θ < π/2), as shown in the figure. (a) For a given θ, what is the minimum F required? (b) For what θ is this minimum F the smallest? What is the corresponding minimum F? Answers a) Fmin = Mg μscos⁡θ+sin⁡θ b) θ = tan−1 ⁡1/μs, Fmin = Mg μs2+1
