The coefficient of kinetic friction between a suitcase and the floor is 0.272. If the suitcase has a mass of 50.0 kg, how far can it be pushed across the level floor with 620 J of work?
The coefficient of kinetic friction between a suitcase and the floor is 0.272. You may want to review (Pages 196 - 203). Part A If the suitcase has a mass of 60.0 kg , how far can it be pushed across the level floor with 670 J of work? V AEO o ? m Submit Request Answer
A 60kg box rests on a floor with a coefficient of kinetic friction of 0.600 and a coefficient of static friction of 0.800. What horizontal force is required to start the box moving? Please show work!
If the coefficient of kinetic friction between a 33.0 kg crate and the floor is 0.360, what horizontal force is required to move the crate at a steady speed across the floor?
You push a 67 kg box across a floor where the coefficient of kinetic friction is uk = .55. The force you exert is horizontal. (a) How much power is needed to push the box at a speed of .50 m/s? (b) How much work do you do if you push the box for 35 s? *please list the steps to work out this question.
explain how you would find the coefficient of static friction and coefficient of kinetic friction between two surfaces. clearly describe what needs to be done and used.
Juana slides a crate along the floor of the moving van. The coefficient of kinetic friction between the crate and the van floor is 0.120. The crate has a mass of 56.3 kg and Juana pushes with a horizontal force of 133 N. If 73.4 J of total work are done on the crate, how far along the van floor does it move?
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
A 16.0-kg block rests on a level floor; the coefficient of kinetic friction between the block and the floor is 0.463. A force of 200 N acts for 4.00 m. How fast is the block moving after being pushed 4.00 m? Assume it starts from rest. (Express your answer to three significant figures.)
A 1,440-N crate is being pushed across a level floor at a constant speed by a force of 250 N at an angle of 20.0° below the horizontal;(a) What is the coefficient of kinetic friction between the crate and the floor?(b) If the 250-N force is instead pulling the block at an angle of 20.0° above the horizontal, as shown in the figure (b), what will be the acceleration of the crate? Assume that the coefficient of friction is the...
