1. The problem statement, all variables and given/known data Hi, I conducted a circular motion experiment--with a rubber bung & string through a plastic tube. I changed the radius of the string every trial, calculated the amount of time for one revolution, and from that derived velocity and velocity^2. With my data, I graphed Velocity^2 against Radius. I found a linear line of best fit for the graph. From here, how should I proceed to obtain the formula acceleration = V^2/r? Thanks!
