4) Apple and Orange are asked to determine the coefficient of friction between a box and a ramp at an angle 0 as shown. a) The dot at right represents the block on the incline. Draw a free-body diagram showing and labeling the forces exerted on the block. Draw the relative lengths of all vectors to reflect the relative magnitudes of all the forces. b) What equipment (materials) do the students need in order to collect data so that they can calculate the coefficient of friction, u. (Only list materials and what they will be used for) c) Write a step-by-step procedure that Apple and Orange can follow in order to collect the data. d) How do Apple and Orange use the data to determine u? (What equation, Physics principle(s) that they can apply to solve for u) e) Scenario: They collected the data when the box slid down the ramp, and calculate u as shown in part d, but the result showed that u >1. Would it be possible for u > 1 when the box did slide down the ramp? If no, explain what could cause the error? (the sources of error)
