A puck of mass m=180g on a horizontal, frictionless table is connected to a string that passes through a small hole in the table, as shown in the following figure (attached) The puck is set into circular motion of radius R=50cm with a speed vi = 2.2 m/s. If the string is then pulled from the bottom as shown, so that the radius of the circular path is decreased to r=20cm, what is the final speed, vf, of the puck?

Centripetal Force

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 force.
