Hey everyone,(adsbygoogle = window.adsbygoogle || []).push({});

Okay, so i'm just not sure how to solve this problem exactly and could use some kind advice.

A heavy ball is connected on the end of a light rope and undergoing rotation witha radius of X, let's say. At t= 19.3s a=10.2m/s^2. At t=7.4s what was the acceleration.

How does one go about solving this problem? Thanks in advance.
