A small block with mass 0.130 kg is attached to astring passing through a hole in a frictionless, horizontal surface . The block is originally revolving in a circle with a radiusof 0.800 m about the hole with a tangential speed of 4.00 m/s. Thestring is then pulled slowly from below, shortening the radius of thecircle in which the block revolves. The breaking strength of the string is30.0 N. What is the radius of the circle when the string breaks?
