Be clear and concise but include an adequate explanation. (a) Did your F vs a plot go through (0,0)? Should it? Why/why not? (b) If the F vs a plot has a positive intercept on the y-axis, what parameter does this intercept physically represent? Explain. Note questions asks not mathematically, but physically. (c) If extra mass was added on the cart and the same experiment conducted, how would the slope of F vs a graph change? (d) If the cart was pulled/pushed so it moved with constant velocity, does it mean there is no force applied? Explain.EXPERIMENT A cart equipped with an Accelerometer (which measures acceleration) and a Force sensor (which measures force) is placed on the table. Once all the instruments are calibrated, the cart is pushed and pulled along a straight line on a horizontal tabletop in a setup shown below. The acceleration and the applied force are recorded simultaneously. A digital scale is used to measure the mass of the cart as well. Force Sensor Accelerometer
