A crate of mass 100kg is at rest on a horizontal floor. The coefficient of static friction between the crate and the floor is 0.4, and the coefficient of kinetic friction is 0.3. A horizontal force, F, or magnitude 350N is applied to the crate. Which of the following is true?
A. The crate accelerates horizontally at 0.5m/s^2
B. The crate slides across the floor at .5m/s
C. The crate does not move.
Please give the correct answer and an explanation why it is correct.

max static friction force = .4*981
which is more than 350
so
It stays in place. 350 N might be enough to keep it moving, but is not enough to start it. 👍
