38. A constant torque of 25.0 N • m is applied to a grindstone whose moment of inertia is 0.130 kg m?. Using energy principles, and neglecting friction, find the angular speed after the grindstone has made 15.0 revolutions. (Hint:
the angular equivalent of Wet = FAx = mu? - mu? is
Wner = TAO = 4107 - 1107. You should convince
