You have an unlimited number of submissions to enter the correct answer. If you answer incorrectly at first, make sure to read the Comments before trying again. Hint: • Make sure to select Trial #9. • Measure the angular displacement of the large disk using the protractor tool. It is strongly recommended that you use the 8x Slow Motion speed version of your trial. • You must convert the angular displacement to radian \(rad\) units; here's a useful conversion factor: $\pi \text{ rad} = 180^\circ$ • Measure the elapsed time using the stopwatch tool. • Calculate the angular velocity using these measured values with the equation $\omega = \frac{\Delta \theta}{\Delta t}$
