The earth has a radius of 6.38e6 and turns on its axis once every 23.9h. A) what is the tangential speed in m/s of a person living in ecuador a country that lies on the equator? B) At what latitude is the tangential speed 1/3 that of a person living Ecuador?Does the tip of a rotating fan blade have a tangential acceleration when the blade is rotating a) at a constant angular velocity and b) at a constant angular acceleration? Provide reasons for your answers. A fanblade is rotating with a constant angular acceleration of +12.0 rad/s^2. At what point on the blade measures from the axis of rotation does the magnitude of the tangential acceleration equal that of the acceleration due to gravity
