6. A 2-kg ball B is traveling around in a circle of radius r1 = 1 m with a speed (vB)1 = 2 m/s. If the attached cord is pulled down through the hole with a constant speed vr = 0.5 m/s, determine how much time is required for the ball to reach a speed of 4 m/s. How far r2 is the ball from the hole when this occurs? Neglect friction and the size of the ball.
