## Homework Statement

These two problems are inclined plane problems which I cannot figure out. The problems are attached in the image below.

## Homework Equations

Fnet=ma

## The Attempt at a Solution

I first broke down the gravity force into its x and y components. After that, I did this:

mgsinx-F(kinetic friction)=ma

and found the expression for normal force: N=mgcosx

then found the expression for F(kinetic friction): mgcosxµk

I tried plugging in the expression for kinetic friction:

mgsinx-mgcosx(µk)=ma

I wasn't able to find an answer using this method so now I have no clue how to proceed.
