1. So the problem is rather simple. And the descriptive solution is a piece of cake. But I need help finding the mathematical relationship that exists between the mass of the pulley, mass of the cart, and the acceleration. In other words our lab consisted of a cart which had a mass of 500 grams. We had to see what happened to the acceleration when the mass on the pulley increased. Obviously the acceleration increased so when graphed with acceleration on the y-axis and mass of the pulley on the x-axis the line is going in the positive direction. As you can see I can describe what happens when we vary these different variables but I don't know the equation my teacher wants. He said for me to find the slope of each of my graphs. So I did that- for the graph with the cart of 500 grams it has a slope of .00604, for the cart with 600 grams it has a slope of .00572, for the cart of 700 grams it has a slope of .00558. For the cart of 1000 grams it has a slope of .00469. Lastly the cart with 1500 grams has a slope of .00368. As you can see it decreases as the mass of the cart increases. Now how do i incorporate that slope into a mathematical equation to show the relationship. Please help! thanks ( by the way its due tomorrow!)
