A turbine in an electric power plant rotates at 3600 rpm. Discover its angular speed in radians/second, and decide the linear speed of a point 72cm from the axis of rotation. The power plant shuts down, and the turbine coast to a halt in 590s. If the angular acceleration is constant, how many revolutions does the turbine make through this time?
