Homework Statement
a block of unknown mass is given a push up a 40 degrees inclined plane and then released.
it continues to move up the plane (+) at an acceleration of -9m/s squared.what is the coefficient of kinetic friction ?
Homework Equations
f(friction) + mg cos 50 - F = -9 (m)
n = mg sin 50
f( kinetic friction)= (kinetic friction constant) .normal force (n)
The Attempt at a Solution
i have used the above mentioned equations but i couldn't find the right answer..
sooo,, am looking forward for any help guys...
