A 100 g ball on a 60-cm-long string is swung in a vertical circle about a point 200 cm above the floor. The tension in the string when the ball is at the very bottom of the circle is 5.0 N. A very sharp knife is suddenly inserted, as shown in FIGURE P8.56, to cut the string directly below the point of support. How far to the right of where the string was cut does the ball hit the floor?

A 100 g ball on a 60-cm-long string is swung in a vertical circle about a point 200 cm above the floor.

You are watching: How far to the right of where the string was cut does the ball hit the floor?
