It begins to accelerate ata constant rate (that 15, a constant angularacceleration) as it makes lts way halfwayaround the track. It then decelerates at thesame constant rate during the second halt ofthe lap. It completes the entire lap in a time of28.5 seconds. What is the car's top total (net)acceleration?A) 4.60 m/s^2B) 1.30 m/s^2C) 8.17 m/s^2D) 8.27 m/s^2

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.
