1. The problem statement, all variables and given/known data During a sustained wind the blades on a two blade horizontal–axis wind turbine is turning with an angular velocity of 5 rad/s. If initially the blades have an angular velocity of 2 rad/s, determine the distance point P on the tip of the blade has travelled in 3.0 seconds. Also, what is the magnitude of the acceleration of this point when t = 3.0 seconds. Point P is the Tip of the blade. Radius is 4.55m. 2. Relevant equations where w=omega (angular velocity in rad/s) w=v/r L=Iw 3. The attempt at a solution Initially we have 2rad/s wr=v 2rad/s * 4.55m=9.1 m/s 5rad/s *4.55m= 22.75m/s I don't understand how to answer the question considering there is no information given on how fast it accelerates to 5rad/s. Does it instantly go to 5rad/s Any insight?
