So from here I need to find the kinetic and static friction. The problem for me is that I dont know where to start. When I try do find Fx and Fy, I need the mass, so which way should I go through?

Thanks! :)

What does the problem ask you to find? The coefficient of kinetic friction?

The problem wants me to find the coefficient between the chuck and the inclined plane

Good.The problem wants me to find the coefficient between the chuck and the inclined plane

(1) Figure out the acceleration.

(2) Draw a free body diagram and then apply Newton's 2nd law.

I found the problem. Forgot to multiply cos(theta) with with g. Got the right answer. Thank you soo much! :)
