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 ?

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal for…
