A 4.00 kg box sits at rest at the bottom of a ramp that is 9.00 m long and is inclined at 30.0° above the horizontal. The coefficient of kinetic friction is mk = 0.40, and the coefficient of static friction is ms=0.43
Part A 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 6.00 s?​
