The ball is making a circular motion. The centripetal acceleration in a circular motion is

$a = \frac{v^2}{r}$

$a = \frac{20^2}{0.7} = \frac{400}{0.7} = 571.4~ m/s^2$ ~

Explanation:

Normally in physics questions like this, we use all the information in the question. Here, we left out the mass or the height of the object. I assume there is more sub-questions that is not shared here. However, the centripetal acceleration can be found by using the velocity and the radius only.

We use measurements in our lives daily because the measurements help define what the length of something is.
