finding expression for force and magnitude

Question

A book with mass m = 1.25 kg rests on the surface of a table. The coefficient of static friction between the book and the table is μ_s = 0.79 and the coefficient of kinetic friction is μ_k = 0.47.

Write an expression for Fm the minimum force required to produce movement of the book on the surface of the table.

Solve numerically for the magnitude of the force Fm in Newtons.

Write an expression for a, the book's acceleration, after it begins moving. (Assume the minimum force, Fm, continues to be applied.)

Solve numerically for the acceleration, a in m/s2.
