Homework Statement
A 12-g coin slides upward on a surface that is inclined at an angle of 12° above the horizontal. The coefficient of kinetic friction between the coin and the surface is 0.23; the coefficient of static friction is 0.35. Find the magnitude and direction of the force of friction after it comes to rest.
The Attempt at a Solution
So I thought the answer would be mg cos [tex]\Theta[/tex] * the coefficient of static friction however that isn't getting me the correct answer.
Help please.
Thanks. :)
