A ball of mass 3.0 kg is tied to the end of a 50-cm length of string. The ball and string are swung in a circle in a vertical plane at constant speed V, which is the minimum speed necessary to keep the string taut at all times. The center of the circle is a distance - 190 cm above the floor. Suddenly, the string is released at the instant the ball is at the top of the loop. How far to the right of the center of the circle does the ball hit the ground?
0.0 cm
150 cm
