If the center of the windmill is rotating at 1.67 rad/s CW, what is: Answers: a) the angular speed of the center of the windmill? [rad/s] 1.67 speed has no direction! b) the angular speed of the tip of one blade? [rad/s] 1.67 all points have the same w ! c) the angular speed of a point 3.95 m from the 1.67 center? [rad/s] all points have the same w ! d) the linear speed of the center of the windmill? [m/s] 0.00 e) the linear speed of the tip of one blade? [m/s] 12.9 f) the linear speed of a point 3.95 m from the center? [m/s] 6.60 g) the amount the windmill spins in 4.97 s? [rad] 8.30 h) the distance traveled by the tip of one blade in 64.3 4.97 s? [m] i) the angular acceleration of the tip of one blade? [rad/s ] 0.00 j) the magnitude of the linear acceleration of the tip of one 21.6 blade? [m/s2] lac: towards the center
