## Homework Statement

A block of mass

*M*= 2 kg is on a stationary inclined plane inclined with an angle

*θ*= 30°. A horizontal rope is attached to the block and is pulled to the right with tension

*T*. The tension remains horizontal even in the event that the block moves down the plane. The coefficient of static friction between the block and the inclined plane is

*μs*= 0.7 and the coefficient of kinetic friction is

*μk*= 0.5 .

## Homework Equations

f=ma

## The Attempt at a Solution

I set up the FBD and summed the y component of force but where I get stuck is the tension. Because I know that it has a y component based on my axis but I am not sure how to find it, which is what I am trying to figure out. I am confident that I would understand the rest. for sum of fy i have Nf-mgcos(30)=0 and am not sure how to include the tension. I uploaded the FBD of the box
