a dog drags its bes box across a floor by applying a horizontal force of 4.5N. the kinetic frictional force acting on the box has magnitude 2.7N. As the box is dragged through 0.76m along the way, what are (a) the work done by the dogs applied force and (b) the increase in thermal energy of the bed and floor?
3- A 45 kg crate is dragged at constant velocity 8.2 m across a horizontal floor due to an horizontal force F = 100 N. If the coefficient of kinetic is 0.25. Find: a. The work done for each force acting on the crate. b. The total work done on the crate
You are pushing a refrigerator across the floor of your kitchen. You exert a horizontal force of 297 N for 6.3 s, during which time the refrigerator moves a distance of 2.9 m at constant velocity. (a) What is the total work (by all forces) done on the refrigerator? J (b) What is the work done by friction? J
A 190 kg block is pulled at a constant speed of 4.3 m/s across a horizontal floor by an applied force of 104 N directed 24° above the horizontal. What is the rate at which the force does work on the block?
A 170 kg block is pulled at a constant speed of 1.1 m/s across a horizontal floor by an applied force of 106 N directed 31° above the horizontal. What is the rate at which the force does work on the block?
At the airport, you drag your 17.1 kg suitcase across the floor at a constant velocity using a strap that is at an angle of 47.1o above the horizontal. If the coefficient of kinetic friction between the suitcase and the floor is 0.352, what is the tension in the strap? How much work does the force of kinetic friction do on suitcase if you drag it 20 m? TENSION IN THE STRAP IS 62.9, PLEASE HELP SOLVE FOR WORK.
A 91 kg block is pulled at a constant speed of 1.2 m/s across a horizontal floor by an applied force of 109 N directed 38° above the horizontal. What is the rate at which the force does work on the block? please show work step by step when answering
A 1,020-N crate is being pushed across a level floor at a constant speed by a force F of 210 N at an angle of 20.0° below the horizontal, as shown in the figure (a) below. 20.0° 120,0 (a) What is the coefficient of kinetic friction between the crate and the floor? Your response differs from the correct answer by more than 10%. Double check your calculations. (b) If the 210-N force is instead pulling the block at an angle...
A person pulls a 17.0 kg box 5.0 m across a horizontal floor with a tension force 19 N directed at 40 degrees above the horizontal. The work done by this force is __________. (Include the appropriate SI unit.)
1a . A constant force of 32.3 N pulls on a 20 kg block on a horizontal surface. The force is directed at 30o above the horizontal. A friction force impedes the motion. If at the start of the motion the block was at rest and after 11 meters it has a velocity of 3, what is the coefficient of friction? 1b. What is the work done by the constant force when the block is moved 8 meters? 2.What constant,...
