None Problem 4A woman attempts to push a box of books that has mass 33.0 kg up a ramp inclined at an angle of 28.5 degrees above the horizontal.Assume that the coefficients of friction between the ramp and the box are unknown, and symbolize them by μ, andby the woman is HORIZONTAL, i.e. parallel to the ground, not to the ramp.The force F appliedPart AIf μ, is greater than some critical value, the woman cannot start the box moving up the ramp no matter how hard she pushes. Calculatethis critical value of μ. Note: this critical value of μ, may be an unreasonably large value; i.e. something much larger than 1.0.ΜΕ ΑΣΦ?
