A circular disk spinning in the vertical plane is used to launch masses along a vertical tangent. The disk has a diameter of 0.50 m and the marble to be launched has a mass of 14.5 g. The disk is initially at rest, then it is accelerated at 750 rad/s2. If the marble is launched after 0.5 revolutions, calculate the maximum height attained above the launch point.
