Compute each part of given problem:
Problem: Imagine there are rocks sliding and they are approaching the base of a hill with a speed of 13.0 m/s. The hill rises at 43.0 degree above the horizontal and has coefficients of kinetic and static friction of 0.370 and 0.640, respectively, with these rocks. Start each part of your solution to this problem with a free-body diagram.
Part A: Find the acceleration of the rocks as they slide up the hill.
Part B: If it slides down, find its acceleration on the way down, else enter 0.
I need help obtain the acceleration of the rocks as they slide up the hill.
