1. Compare the accelerations for the three trials. Explain how Newton's second law was demonstrated in the simulation? 2. Describe how Newton's first and third laws would apply to this situation if this simulation was done in the real world. 3. Compare the masses that you calculated for the three trials. If the actual mass of the cart did not change (same cart for all trials), what measurement do you believe contributed the largest amount of error to that calculation? Explain your
