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:
mgsinxF(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:
mgsinxmgcosx(µk)=ma
I wasn't able to find an answer using this method so now I have no clue how to proceed.
