A force of 40.0N accelerates a 5.0-kg block at 6.0M/s^2 along a horizontal surface.
a. What is the frictional force?
b. What is the coefficient of friction?
u= coefficient of friction
m= mass of object
Ff= friction force
The Attempt at a Solution
I used u=Ff/mg and i got 1.3 for the u. but that is when i used the given acceleration of 6.0 m/s^2, not gravity. is that correct?
