Planar Kinematics of a Rigid Body (PKRB)
4.

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.

vP = 5.60 ft/s
vP = 19.87 ft/s
vP = 14.05 ft/s
vP = 18.81 ft/s
