Concept explainers

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.

Question

An athlete swings a ball, connected to the end of a chain, in a horizontal circle. The athlete is able to rotate the ball at the
rate of 8.54 rev/s when the length of the chain is 0.600 m. When he increases the length to 0.900 m, he is able to rotate
the ball only 6.59 rev/s.
(a) Which rate of rotation gives the greater speed for the ball?
O 6.59 rev/s
8.54 rev/s
(b) What is the centripetal acceleration of the ball at 8.54 rev/s?
m/s²
(c) What is the centripetal acceleration at 6.59 rev/s?
m/s²
