3. A block is being pulled by a string across a horizontal rough surface (friction is significant) so that the block accelerates. a. Draw a force diagram for the block. b. You are tasked to design an experiment for this situation in which you can graphically solve for both the mass of the block and the coefficient of static friction. Create an equation that relates these two unknowns to other physical quantities we can measure experimentally. c. Below is a table of forces exerted on the block by an external force and the measured acceleration. d. What would you plot on the x and y axis to find the value of the unknown (but constant) mass of the block and the coefficient of friction? d. Calculate these values Force (N) Acceleration (m/s^2) 0.9 1.1 1.5 1.15 1.8 1.2 2.1 1.3 2.5 1.35 2.7 1.4 3
