Object dragged on surface with friction

an object with a mass of 150kg is pushed upon by a force F. if the coefficients of friction between the object and the surface are found to be [math]\mu_S = 0.40[/math](static) and [math]\mu_k = 0.28[/math](kinetic) how fast does the object accelerate as it is being pushed if:

A) F = 300N
B) F = 1000N
