A rocket powered car is set inside a circular track and ignited. Pressure sensors on the wall of the track measure the centripetal acceleration of the car as a function of time to be   ?c(?)=(4 m/s6)?4+(28 m/s4)?2+(49 m/s2)   If the radius of the track is 3.28 m, what is the tangential acceleration of the rocket car at ?=5.51 s?

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.
