In а lаb, а student investigates Newtоn’s Secоnd Law by pulling a sled оf known mass across a frictionless surface using a spring scale. The sled’s mass is measured as 0.750 kg. The student records the following data: Applied Force (N) Measured Acceleration (m/s2) 1.00 1.30 2.00 2.65 3.00 3.85 4.00 5.10 Using Newton’s Second Law, calculate the theoretical acceleration of the cart for each applied force.  Compare the measured accelerations with the theoretical accelerations by finding the percent error for each data point. Determine the average percent error across all four trials. Based on this result, evaluate whether the data supports Newton’s Second Law. Suppose the experiment was repeated on a track with noticeable friction. Explain how this would affect the slope if the student plotted force vs. acceleration and fit a straight line to the plot.
