1.) The problem statement, all variables and given/known data A(n) 2.71 m long pendulum is released from rest when the support string is at an angle of 35.8◦ with the vertical. The acceleration of gravity is 9.8 m/s2 . What is the speed of the bob at the bottom of the swing? Answer in units of m/s 2.) Relevant equations Not sure 3.) The attempt at a solution I tried to do 2.71sin(35.8) and I got 1.585. It's not the right answer. I also tried to do do cos(35.8) but that did not work either. Are there any other equations I have to use to find the speed of the bob?
