A horizontal force fo 190N is needed to pull a 70kg box across a horizontal floor at a constant speed. What is the coefficent of friction between the box and the floor?
Fnet = ma
The Attempt at a Solution
My setup is F - F_f = m*a
But I have trouble getting the acceleration.....
F_f is supposed to be F_f = N * u
I am guessing F_f is knifectic fricition? Is it 190N?
I am confused. Please help!
