How does the diameter of the bob have anything at all to do with the velocity?

Yeah, I know that. My problem is that I can't figure out how to get the speed, because I don't know the distance that the bob has travelled. Is it actually possible to determine the speed with the information that I have?

Hi, there. I'm doing a correspondance physics course, and this one question has me stumped. I'm calculating the efficiency of a pendulum, and therefore need to find the mechanical energy, as well as the thermal energy. However, I don't think they've given me enough information. Mass of...
