Physics

A box of mass 18.0 kg sits at rest on a horizontal surface. Thecoefficient of kinetic friction between the surface and the box is0.300. The box is initially at rest, and then a constant force ofmagnitude FF and direction 39.0 ∘∘ below the horizontal is appliedto the box; the box slides along the surface.

A. What is F if the box has a speed of 6.00 m/s after travelinga distance of 8.00 mm? Express your answer with the appropriateunits.

B. What is FB if the surface is frictionless and allthe other quantities are the same? Express your answer with theappropriate units.

C. What is FC if all the quantities are the same asin part A but the force applied to the box is horizontal? Expressyour answer with the appropriate units.
