(adsbygoogle = window.adsbygoogle || []).push({}); A pendulum is 0.7 m long and the bob has a mass of 1.0 kg. At the bottom of its swing, the bob's speed is 1.6 m/s. What is the tension in the string at the bottom of the swing?

I know that I can use centripetal force, which can be calculated from v -

ma(c) = (mv^2)/r

I get 3.6571 N as my answer, why is this wrong? thanks
