I have no idea how to do this problem. What equation do I use?(adsbygoogle = window.adsbygoogle || []).push({});

The pendulum on my clock is 20 cm long. At the top of the swing, it makes an angle of 10 degrees with the verticle. What is the speed of the pendulum at the bottom of the swing?

The answer is 0.24 m/s, but how?

Thank you.
