A small block with mass 0.290 kg is attached to a string passing through a hole in a frictionless, horizontal surface (Figure 1). The block is originally revolving in a circle with a radius of 0.800 m about the hole with a tangential speed of 4.00 m/s. The string is then pulled slowly from below, shortening the radius of the circle in which the block revolves. The breaking strength of the string is 30.0 N. Part A What is the radius of the circle when the string breaks? Express your answer with the appropriate units. T = ΜΑ Value Units ?
