A4-lb ball b is traveling around in a circle of radius r1 = 3 ft with a speed (vb)1 = 6 ft/s. if the attached cord is pulled down through the hole with a constant speed vr = 2 ft/s, determine how much time is required for the ball to reach a speed of 12 ft/s. how far r2 is the ball from the hole when this occurs? neglect friction and the size of the ball.
