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.

A pendulum consists of a small object called a bob hanging from a light cord of fixed length, with the top end of the cord fixed, as represented in Figure OQ6.4.

The figure shows a 100 g puck revolving in a 20 cm radius circle on a frictionless table. The string passes through a hole in the center of the table and is tied to two 200 g weights.

What will be the puck's speed after all of the sand is gone?
