[tex]\tt{\huge{\blue{Explanation:}}}[/tex]
The centripetal acceleration of an object is given by
[tex]\boxed{a_{c} = \frac{v^{2}}{r}}[/tex]
where:
ac = centripetal acceleration
v = speed
r = radius
[tex]\tt{\huge{\red{Solution:}}}[/tex]
Solving for centripetal acceleration
[tex]a_{c} = \dfrac{v^{2}}{r}[/tex]
[tex]a_{c} = \dfrac{(\text{20 m/s})^{2}}{\text{5 m}}[/tex]
[tex]\boxed{a_{c} = \text{80 m/}\text{s}^{2}}[/tex]
Therefore, the centripetal acceleration is 80 m/s²
