A1000N crate is being pushed across a level floor at a constant speed by a force of 300N at an angle of 20 degrees below the horizontal.(adsbygoogle = window.adsbygoogle || []).push({});

(a) what is the coefficient of kinetic friction between the crate and the floor

I was able to find this which is = .26

(b) If the 300N force is instead pulling the block at an angle of 20 degrees above the horizontal what will the acceleration of the crate be?(assume that the coefficient of friction is the same as found in (a))

Help I need guidance on this part!
