A rotor with a fixed spin axis identified by point O is accelerated from rest with an angular acceleration αO = 0.5 rad/s2. If the rotor’s diameter is d = 15 ft, determine the time it takes for the points at the outer edge of the rotor to reach a speed υ0 = 300 ft/s. Finally, determine the magnitude of the acceleration of these points when the speed υ0 is achieved.
