Harnessing wind power has become an effective alternative to finding and refining fossil fuels. These wind turbines are now found all over Ontario. One of these turbines has a blade with an 8 metre diameter. The maximum height from the ground to the tip of the blade is 26 m. At an average wind speed, the blade makes 20 rotations every minute. Assuming that the tip of the blade starts at the lowest point, determine an equation for the height versus time.A 2kg toy is moving in a circle of radius 2.5 m with a speed of 3m/s.Calculate the centripetal acceleration of the toy? choose one correct answer with the correct units.
