Hello, I plotted a graph that gave me force vs. position but I need to make it so it gives me force vs. time but I am not sure on how to convert the time. I am given the sample rate which is 20 samples per second and the crosspeed is 15 inches per minute. but if the sample rate fluctuates, how can I obtain the actual distance ? I hope this makes sense, anything helps

% correct and the graphs do not match up

% Import the data
