A force of 30 N accelerates a 5.0-kg block at 5.0 m/s2 along a horizontal surface.
How large is the frictional force?
(b) What is the coefficient of friction?
I am not relly sure of the equations used..
The Attempt at a Solution
Well first i calculated the F Net which would be the mass * 9.8 in this case it was 5.0kg * 9.8 which is 49N, then i did 30N/49N which was .6122 apparently that is the the coefficient, and calculating (a) I have no idea
