Problem 51P

A 60 g ball is tied to the end of a 50-cm-long string and swung in a vertical circle. The center of the circle, as shown in FIGURE, is 150 cm above the floor. The ball is swung at the minimum speed necessary to make it over the top without the string going slack. If the string is released at the instant the ball is at the top of the loop, how far to the right does the ball hit the ground?

Step 1 of 5

The objective here is to determine the horizontal distance at which a ball will hit the ground, after it is released from the string, at the top of a circular loop.
