Question

which formula can be used to find the centripetal acceleration of an orbiting object?
( a_{c}=\frac{sqrt{v}}{t} )
( a_{c}=\frac{v^{2}}{t} )
( a_{c}=\frac{v^{2}}{r} )
( a_{c}=\frac{sqrt{v}}{r} )

Explanation:

Step1: Recall centripetal acceleration formula

Centripetal acceleration formula is \(a_{c}=\frac{v^{2}}{r}\) where \(v\) is the tangential velocity and \(r\) is the radius of the circular path.

Answer:

\(a_{c}=\frac{v^{2}}{r}\) (the third option)
