During a gust of wind, the blades of the windmill are given an angular acceleration of  = (0.2  ) rad/s², where  is measured in radians. If initially the blades have an angular velocity of 5 rad/s, determine the speed of point P located at the tip of one of the blades just after the blade has turned two revolutions.
