Answer:
The ball is making a circular motion. The centripetal acceleration in a circular motion is
[tex]a = \frac{v^2}{r} [/tex]
[tex]a = \frac{20^2}{0.7} = \frac{400}{0.7} = 571.4~ m/s^2[/tex]~
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.
