During a gust of wind, the blades of the windmill are given an angular acceleration of _{} = (0.2 _{} ) rad/s^{2}, 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.

[A].

v_{P} = 5.60 ft/s

[B].

v_{P} = 19.87 ft/s

[C].

v_{P} = 14.05 ft/s

[D].

v_{P} = 18.81 ft/s
