A 5.80-kg box sits at rest at the bottom of a ramp that is 8.20 m long and that is inclined at 40.0 ∘ above the horizontal. The coefficient of kinetic friction is μk = 0.40, and the coefficient of static friction is μs = 0.43.

What constant force F , applied parallel to the surface of the ramp, is required to push the box to the top of the ramp in a time of 4.00 s ?
