Could someone credible please check my work on this one?
This problem is "pulling a sled up a slope"
All relevant data is in the picture. I wanted to find FP (The force one has to pull to start the sled moving up with slope).
mass = 26.0kg
μs = 0.096
slope of hill = 12 degrees
FP = 23 degrees (from horizontal)
I did all my work in the rotated reference frame where the x direction is in line with the slope of the hill.
I fully believe I got the right answer which is why I want this to be double and triple checked to make sure I really do understand everything here. I have my midterm on Friday so now is the time to learn!
The Attempt at a Solution
The solution I got was FP = 76.9N
Thank you so much in advance! <3‿<3
