1. The problem statement, all variables and given/known data A circular pendulum of length 1.2 m goes around at an angle of 25 degrees to the vertical. Predict the speed of the mass at the end of the string. Use g = 9.8 m/s2. Answer in units of m/s 2. Relevant equations 1/2mv^2 = mgh h = L - Lcosθ 3. The attempt at a solution I used the above formula doing: 1/2mv^2 = mgh v = √2g(L - Lcosθ) Plug n' chug: v = √2*9.8*(1.2 - 1.2cosθ) v = 1.448 m/s I've seen variations of this problem before, but I'm not really sure what I'm doing wrong.
