A factory worker pushes a 30.0 kg crate a distance of 5.7 m along a level floor at constant velocity by pushing downward at an angle of 30 degrees below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.25. How much work is done by gravity? What is the total work done on the crate?
A factory worker pushes a 30.0 kg crate a distance of 4.5 m along a level floor at constant velocity by pushing downward at an angle of 30° below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.25. Part A What magnitude of force must the worker apply to move the crate at constant velocity? Part B How much work is done on the crate by this force when the crate is pushed a distance of 4.5 m? Part C How...
Please show work for each part. A factory worker pushes a 26.5-kg crate a distance of 4.3 m along a level floor at constant velocity by pushing horizontally on it. The coefficient of kinetic friction between the crate and the floor is 0.27 Suppose the worker pushes downward at and angle of 340 below horizontal. (a) What magnitude of force must the worker apply? (b) How much work is done on the crate by this force? (c) How much work...
A factory worker pushes a 29.3 kg crate a distance of 4.1 m along a level floor at constant velocity by pushing downward at an angle of 28 ∘ below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.25. 1) What magnitude of force must the worker apply to move the crate at constant velocity? 2) How much work is done on the crate by this force when the crate is pushed a distance of...
A factory worker pushes a 28.1 kg crate a distance of 4.1 m along a level floor at constant velocity by pushing downward at an angle of 31 ∘ below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.26. Part A: What magnitude of force must the worker apply to move the crate at constant velocity? Part B: How much work is done on the crate by this force when the crate is pushed a...
Just asking help with Part I A factory worker pushes a 30.0 kg crate a distance of 4.40 m along a level floor by pushing downward at an angle of 28.0° below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.260. The Crate is Pushed with Increasing Speed Now assume that, instead of the previous situation, the worker pushes harder (without changing the direction of his push), so that the crate moves with increasing speed....
A factory worker pushes a crate of mass 32.0 kg a distance of 4.20 m along a level floor at constant velocity by pushing horizontally on it. The coefficient of kinetic friction between the crate and floor is 0.25. What magnitude of force must the worker apply? Express your answer using two significant figures. F = N Part B How much work is done on the crate by this force? Express your answer using two significant figures. W = J ...
2. A factory worker pushes a 40.0 kg crate a distance of 4.5 m along a level floor at constant velocity by pushing horizontally on it. The coefficient of kinetic friction between the crate and the floor is 0.25. (a) What magnitude of force must the worker apply? (1 mark) (b) Write the force in part (a) as a row vector (1/2 mark) (c) Write the displacement as a row vector (1/2 mark) product of two row vectors (1 mark)...
A warehouse worker is pushing a 90.0 kg crate with a horizontal force of 292 N at a speed of v = 0.875 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 0.359. (a) Determine the magnitude and direction of the net force acting on the crate while it is pushed over the rough section of the...
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...
