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?
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 * 50kg)
I figured out Fn = 482.56 (Fn=490 cos 10)
I figured out F//=85.09 (F//=490 sin 10)
I figured out the Acceleration with no friction is 1.70 m/s2 85.09/50
Any help is appreciated, thanks
