A crate that has a mass of m = 3.5 kg rests on a horizontal plane. The coefficient of static friction, μs, is 0.25. A horizontal force, F, is applied to the crate, and it is just enough to get the crate to begin moving.a. write an expression for the sum of the forces in the x-direction using that Ff is the static friction force, FN is the normal force and Fg is the weight.b. write an expression for the sum of forces in the y-direction using the same coordinate systemc. calculate the magnitude of F, in newtons, Ff is at its maximum

A crate that has a mass of m = 3.5 kg rests on a horizontal plane. The coefficient of static friction, μs, is 0.25. A horizontal force, F, is applied to the crate, and it is just enough to get the crate to begin moving.
a. write an expression for the sum of the forces in the x-direction using that Ff is the static friction force, FN is the normal force and Fg is the weight.
b. write an expression for the sum of forces in the y-direction using the same coordinate system
c. calculate the magnitude of F, in newtons, Ff is at its maximum
