In the preceding problem we saw that a person’s reaction time is generally not quick enough to allow the person to catch a $1 bill dropped between the fingers. The 16 cm length of the bill passes through a student’s fingers before she can grab it if she has a typical 0.25 s reaction time. How long would a billneed to be for her to have a good chance of catching it?

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.
