A ball weighing m=20 g, attached to a weightless thread L=50 cm long, rotates in a horizontal plane around a vertical axis with a frequency n1=2 rev/s. Determine the angular velocity and kinetic energy of the ball if the length of the thread is shortened by 3 times, thereby bringing the ball closer to the axis of rotation.
