A 1000-N crate is being pushed across a level floor at a constant speed by a force of 300 N at an angle of 20.0 degrees below the horizontal.(adsbygoogle = window.adsbygoogle || []).push({});

a) What is the coefficient of kinetic friction between the crate and the floor?

b) If the 300 N force is instead pulling the block at an angle of 20.0 degrees above the horizontal, what will be the acceleration of the crate? (Assume that the coefficient of friction is the same as in a)

I have not a clue how to do this problem.
