Homework Statement
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.
Homework Equations
Fnet=m*a
Ffk-kinetic friction force
k-friction coefficient
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 canceled 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.
