That is how I got how fast it will move without friction. a= F/m 1.70 m/s2= 85.09/50kg But my question is how do I figure out the acceleration with friction of .15? Where do I apply the .15 in my equation?

Homework Statement A roof has an incline of 10 degrees. If the µ of friction between a 50kg box and roof is .15, how fast will the box move? Homework Equations Ff=µ * Fn The Attempt at a Solution I have no idea how to get this. I know it very easy. I figured out Fg = 490N (Fg=9.8 *...
