. Run the simulation tool and use the information it provides to find the radius of the rotating flywheel. Be careful to show all of your reasoning and working. (6 marks) Set the angular velocity to 0.3 rad s-1 and the radial velocity to 0.7 ms 1. Press Reset then Play and allow the point to run to its limit. You will see values for the magnitudes of ac and at at the top right of the screen. Show your working to verify these numbers. You may need your answer to part (a) for some of the calculations. (9 marks) Use your results from part (b) to calculate the magnitude and direction (as an angle in degrees in relation to the direction f) for the resultant vector a. (10 marks)
