Your friend is helping you slide a couch 4.7 m across the room. You pull with a force of 225 N at
35° above the horizontal from the front and she pushes from the other end with a force of 315N
at 25 degrees from the horizontal. What is total work done?

Look at Figure El.28 on page 29 of your textbook (reproduced in the figure to the right). Draw vectors B and C. On your drawings, sketch the components B_x, B_y, and C_y Calculate the x and y components of vector B and vector C If E = B + C, draw and calculate the magnitude and direction of vector E. If F = B - C, draw and calculate the magnitude and direction of vector F. You and your friend...
You slide a chair across a rough, horizontal surface. The chair's mass is 18.8 kg. The force you exert on the chair is 165 NN directed 26 degrees below the horizontal. While you slide the chair a distance of 4.70 mm , the chair's speed changes from 1.50 m/sm/s to 2.60 m/sm/s . Find the work done by friction on the chair.
You pull a your friend along in a sled (combined mass is 65 kg), by pulling the rope at an upward angle of 20 degrees with respect to the ground with enough force to keep the sled moving at a constant velocity of <3,0, 0> m/s. The coefficient of kinetic friction between the ground and the sled is 0.15. (a) Draw a force diagram for the friend/sled system. (b) Once you get to constant velocity, you pull the sled 15...
Work on a sliding crate. A worker pushes a 47.0 Kg crate across a level horizontal floor by applying a constant force of exactly 150.0 N at an angle of 23.0 degrees below the horizontal. The crate begins at rest and ends 15.0m from where it started traveling at 2.6m/s A. What is the work done by the applied force as the crate moves across the floor? B What is the work done by the friction force as the crate...
You are helping your friend move a new refrigerator into his kitchen. You apply a horizontal force of 263 N in the negative x direction to try and move the 54 kg refrigerator. The coefficient of static friction is 0.67. A) How much static frictional force does the floor exert on the refrigerator? Give both magnitude (in N) and direction. B) What maximum force (in N) do you need to apply before the refrigerator starts to move?
+x -Axi You pull a box 3 m along a frictionless horizontal surface with 5 N of force. You apply the force to a string attached to the top of the box at a angle of 30 degrees. How much work is done? Your Answer: Answer units
A force of 60 N is needed to slide a 14 kg block along a ramp inclined at 25 degrees above the horizontal. If the length of the ramp is 4 m, calculate the following: How much work is done sliding the block along the ramp How much work is done against the force of friction The IMA of the ramp The AMA of the ramp The Efficiency of the ramp
You are helping your friend move a new refrigerator into his kitchen. You apply a horizontal force of 269 N in the negative x direction to try and move the 59 kg refrigerator. The coefficient of static friction is 0.69. (a) How much static frictional force does the floor exert on the refrigerator? Give both magnitude (in N) and direction. magnitude Considering your Free Body Diagram, how do the forces in each direction compare? (b) What maximum force (in N) do...
please show step by step
will rate asap, thank you
