Question: Suppose you have measured the time (delta T) required for a glider to travel several distances (delta X) down an inclined plane. After plotting the data points on a graph of delta X vs. (delta T)^2, you find the slope of the best fitting straight line is 15cm/s^2. What is the acceleration of the cart down the incline? I am have such difficulty trying to figure out where to start with this problem. I know that slope = rise/run and that Acceleration = the limit of delta V/ delta T, as T goes to zero. If someone could please point me in the right direction to figuring it out, it would be greatly appreciated!
