m R A racing greyhound can run around curves at high speed. Suppose the radius of a semicircular turn on a dogtrack is 21.6 m, and the speed of a greyhound is constant at 15.1 m/s; assume the dog's mass is 22.7 kg. What is the acceleration of the greyhound on the turn? (in m/s^2) OA: 4.487 OB: 5.070 OC: 5.729 OD: 6.474 OE: 7.316 OF: 8.267 OG: 9.342 OH: 10.556

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.
