To get a toolbox up an inclined slope, a student installs a pulley system as in the picture shown. The student uses their body weight to apply a force. The student weighs 88.5kg, and the toolbox weighs 17kg. The angle of the slope is 30.9° above the horizontal. The coefficient of friction between the box and the slope is 0.297. Once the student gets the box moving, what will its acceleration be?

Consider the scenario shown in the diagram below. A box (mass m1) is on a slope, which is inclined at an angle theta with respect to the horizontal. The box is connected via a string and pulley to a hanging weight (mass m2). The string and the pulley are assumed to be massless and frictionless, but there is friction between the box and the incline (with coefficient of kinetic friction mu k). Find an expression for the tension T in...
