Step-by-step explanation:
For an object moving in uniform circular motion, the centripetal acceleration is given by:
![a=(v^2)/(r)](https://img.qammunity.org/2020/formulas/physics/middle-school/i4cb2fhd7cprxg554mccgh9368fchjcnjl.png)
where
v is the tangential speed
r is the radius of the circle
In this problem, we have:
r = 0.146 m is the radius of the circle
v = 1.23 m/s is the tangential speed
Substituting the numbers, we find:
![a=(1.23^2)/(0.146)=10.4 m/s^2](https://img.qammunity.org/2020/formulas/physics/high-school/qbpy4jzp8qmnc7wn8r74lh630drqcu6w3v.png)
