1. The problem statement, all variables and given/known data These two problems are inclined plane problems which I cannot figure out. The problems are attached in the image below. 2. Relevant equations Fnet=ma 3. 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.
