There are two equations for centripetal acceleration. Which equation for centripetal acceleration agrees with the relationship shown in your centripetal acceleration vs radius graph? Why do you think so? ac= 4r / T or ac = v2/r 2. Find the slope of the line of best fit for your graph and write an equation of the line in slope-intercept form. Don't forget to include units for both your slope and your y-intercept. 3. What does your slope represent? Use this to determine the period of the platform. Show all your calculations. 4. Your platform was set with a constant angular velocity of 90 degrees/second. Describe, in your own words, what an angular velocity, w = 90 degrees/second actually means? Determine how long it would take the ladybug to make one full rotation.
