Problem: A 65kg create is to be accelerated at 7 m/s/s up an incline making an angle of 25 degrees with the horizontal. If the coefficient of sliding friction is .2, what force is needed to accomplish this motion?(adsbygoogle = window.adsbygoogle || []).push({});

Well ive tried manipulating this equation to give me either a Ff or an Fn for the mu=Ff/Fn equation. Problem is where its on an incline, i need Facos25 and Fasin25, but i dont have an Fa, all im given is a 7m/s/s. Im a bit stuck and need some help here

Thanks in advance
