(20%) Problem 2: A box of mass 4029 is moving up a slope (which forms an angle 6 =34.5" with the horizontal) subject to the force (in N) F (x) =2.6cos(mc/L), with L =256 cm, directed at an angle a =10.5" measured from the [3 direction of the slope (see gure). The box moves from x.- = 0 to xf = 0.57L while we observe it (with the x-axis parallel to the slope). a Use #5 = 0.38 and M = 0.17for the coefcients of friction and g =9.8mlsz.
