Enter the result in the column labeled mdiff- 2. For each trial, calculate the total mass in grams. Enter the result in the column labeled mT. 3. Using LabQuest, Logger Pro, or graph paper, plot a graph of acceleration vs. maiff, using the Part I data. Based on your analysis of the graph, what is the relationship between the mass difference and the acceleration of an Atwood's machine? 4. Similarly, plot a graph of acceleration vs. mr, using the Part…

Aircraft carriers use catapults to launch jets from their deck. One such catapult accelerates a 18,300 kg aircraft from rest to 72 m/s in 3.1 s. What is the magnitude of the force (in N) required to do this?

Problem 2: A runaway train has a mass of 1.5 × 104 kg and a speed of 5 m/s. How much time does it take for a force of magnitude 1500 N to bring the train to rest?
