Force applied to pushing a crate.
This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!
A 1000 newton crate is being pushed across a level floor at a constant speed by a force of 300 newtons at an angle of 20 degrees below the horizontal
A-what is the coeffecient of kinetic friction between the crate and the floor.
B-if the 300 newton force is instead of pulling the block at an angle of 20 degrees above the horizontal
-What will be the acceleration of the crate assume that the coeffient of friction is the same as found in A.
Hello and thank you for posting your question to Brainmass.
Because I wanted the solution to be as detailed as possible, I attach ...
The two pages solution contains full force diagrams, solution strategy ( a list of steps necessary to reach a solution) and full derivation of the solution.
