Newton's Laws

A box of mass 19.0 kg sits at rest on a horizontal surface. The coefficient of kinetic friction between the surface and the box is 0.300. The box is initially at rest, and then a constant force of magnitude F and direction 33.0 ∘ below the horizontal is applied to the box; the box slides along the surface.

a) What is F if the box has a speed of 6.00 m/s after traveling a distance of 8.00 m?

b) What is the coefficient of kinetic friction that one block exerts on the other?

Express your answers with the appropriate units.
