A crate with mass m= 3.5 kg rests on the surface of a table. The coefficient of static friction between the crate and the table is μs= 0.74 and the coefficient of kinetic friction is μ k= 0.39. Requried:
a. Write an expression for a, the crate's acceleration, after it begins moving. (Assume the minimum force, Fm, continues to be applied.)
b. Write an expression for Fm the minimum force required to produce movement of the crate on the surface of the table.
c. Solve numerically for the magnitude of the force Fm in Newtons.
