To test the effects of high acceleration onthe human body, the National Aeronautics and Space Administration (NASA) constructed a large centrifuge at the Manned SpacecraftCenter in Houston. In this device, astronauts were placed in a capsulethat moved in a circular path with a radius of 15 m. If the astronautsin this centrifuge experienced a centripetal acceleration 9.0 timesthat of gravity, what was the linear speed of the capsule?

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.
