1. The problem statement, all variables and given/known data The only given data is that the incline is 60 degrees steep. I also presumed that there is friction. I made an attempt to solve the problem and would like to know if it is correct. 2. Relevant equations Fnet=m*a Ffk-kinetic friction force k-friction coefficient 3. The attempt at a solution judging by the Ox Axis: Ffk+Gx=m*(-a) m*g*k+m*g*sin(60degrees)=m*(-a) m*g(k+sin(60degrees)=m*(-a) (m gets cancelled out) a=-(gk+gsin(60degrees)) a=-9.8k-8.5 (The acceleration in my case has a negative value since I chose to make the Gx and Ffk positive) Any criticism or correction would be much appreciated.
