1. The problem statement, all variables and given/known data: A simple pendulum has a mass of 0.25 kg and a length of 1.0 m. It is displaced through an angle of 5.0° and then released. 1. What is the maximum speed? 2. What is the maximum angular acceleration? Answer: 0.855 rad/s2 3. What is the maximum restoring force? Answer: 0.214 N 2. The attempt at a solution: I got numbers 2 and 3 right, but I can't figure out number 1. Here's my attempt: m*g*L*sin [tex]\theta[/tex] = 1/2 *m*v2 (0.250)*(9.81)*(1.0)*(sin 5) = 1/2 * (0.250)*v2 0.124 = (0.125)v2 v2 = 1.712 = 1.31 m/s It is incorrect. Can someone please help me as to where I went wrong?
