Pre-lab question part 1 and 2

PreLab Questions 1.) Consider a block with mass M sitting on an incline of angle 6 from horizontal. (a) With a coordinate system along the surface of the incline, draw the free body diagram for the block and derive an equation for the acceleration a of the block. (b) Sketch a plot that shows the expected results of the experiment as a linear line and how to obtain the value of g from said plot. 2.) Determine the angle 6 using the given variables
