A small block with mass 0.200 kg is attached to a string passing through a hole in a frictionless, horizontal surface. The block is originally revolving in a circle with a radius of 0.820 m about the hole with a tangential speed of 4.40 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 35.0 N
What is the radius of the circle when the string breaks?
Explanation / Answer
L=mVr =0.2*4.4*0.82
L=0.7216 Kg-m^2/s
T=L^2/mr^3
35=0.7216^2/(0.2)*r^3
r=0.42 m
