Question: 4. Physics students are performing a lab where they allow a ball to roll down a ramp and record the distance that it has rolled

4. Physics students are performing a lab where they allow a ball to roll down a ramp and record the distance that it has rolled versus the time it has been rolling. The data for one such experiment are shown below. Time 0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 (sec) Distance 0 0.4 1.5 3.2 5.6 8.5 12.6 17.2 22.8 (ft) (a) Determine the equation for the line of best fit. Round your coefficients to the nearest tenth. Also, determine the correlation coefficient. Round it to the nearest hundredth
