A simple pendulum, 2 m in length, is released with a push (i.e. - it has an initial velocity) when the support string is at an angle of 25 degrees from the vertical. If the initial speed of the suspended mass is 1.2 m/s when at the release point, use conservation of energy to find it's speed at the bottom of the swing.(adsbygoogle = window.adsbygoogle || []).push({});

* 2.3 m/s

* 2.6 m/s

* 2 m/s

* .5 m/s

I don't really understand how to use conservation of energy that well, so I need help. How would I apply that for this problem? And how do I solve from there? Any help would be much appreciated. I need it by tomorrow night. Thanks.
