Record the time elapsed and the positions on excel. Create a graph of position vs. time and add a quadratic (polynomial order 2) curve fit equation to the graph. Record the coefficient of the squared term in your excel template. 3. Decrease the mass of the box (hover puck) to 900 grams and increase the hanging mass to 200 grams. Start the motion. Record the time elapsed and the positions on excel. Create a graph of position vs. time and add a quadratic (polynomial order 2) curve fit equation to the graph. Record the coefficient of the squared term in your excel template. 4. Repeat procedure #3 decreasing the mass of the box ( hover puck) by 100 grams and increasing the hanging mass by 100 grams until you have ten runs. Create a graph of position vs. time for each data set and a quadratic (polynomial order 2) curve fit equation. Record the coefficient of the squared term for each hanging mass. 5. Determine the acceleration of the system from the coefficient of the squared term for each hanging mass. 6. Create graph of the acceleration of the system versus the hanging mass. Add linear fit equation to the graph. 7. Use the slope and intercept from the linear fit of (a vs. mi) to determine the acceleration due to gravity "little g" and the coefficient of kinetic friction [k
