1. The length of a simple pendulum is 0.760 m, the pendulum bob has a mass of 365 grams, and it is released at an angle of 12-degree to the verticle. (a) With what frequency does it vibrate? Assume SHM. b) What is the pendulum bob's speed when it passes through the lowest point of the swing? c) What is the total energy stored in this oscillation, assuming no losses?(adsbygoogle = window.adsbygoogle || []).push({});

For a), I used the formula f=1/2pai *(g/L)^(1/2) {I can't type the symbol 3.1415.. and radical} I wasn't sure because I didn't use the angle. For b), I used the formula v=radical F/(m/L). I don't think it is right, either, because of the angle. For c) E=1/2mv^2 + 1/2 kx^2, but how do I find x?

Thanks for help.
