If someone pushes on a box on a horizontal floor with a horizontal force of 17.8 N, but the box does not move, what is the static friction (Fs) between the box and the floor? Explain.
The next question is:
If the box just starts to move with a horizontal force of 29.5 N, what is the maximum static friction (Fs,max)?
I know these are solvable with the current information, but I feel like I'm missing something... I am quite lost. I am not sure what formula can solve these with the given info.
In my textbook, it says Fs = -Fapplied
Does this mean Fs really just equals negative 17.8 N, for the first question?
Thanks!
If it is not moving, the fricion must equal the pushing force.
if it moves at 29.5 N
then
29.5 is the max static force
