Homework Statement
The weight of the crate is 875 N. You push it with a force of magnitude 300 N but it doesn't move
What is the magnitude Fp of the minimum force you need to exert on the crate to make it start sliding along the floor? Let the coefficent of the static friction [tex]\mu[/tex]s betwen the crate and the floor be 0.56 and that of kinetic friction, [tex]\mu[/tex]k, be 0.47
Homework Equations
The Attempt at a Solution
I tried solving it by using the formula fk = [tex]\mu[/tex]kn but it told me that I'm going about the problem wrong. It says that I need to study the condition for which the crate ceases to be at rest, that is, the condition for which static friction ceases to be valid. I used kinetic friction though, so I don't know what to do now.
