1. The problem statement, all variables and given/known data A simple pendulum with mass m = 1.7 kg and length L = 2.42 m hangs from the ceiling. It is pulled back to an small angle of θ = 8.6° from the vertical and released at t = 0. Qn: What is the maximum speed of the pendulum? 2. Relevant equations θ=θmax*cos(ωt+∅) 3. The attempt at a solution i derivative the equation i got θ=θmax*ω*sin(ωt) the ω outside i know is angular velocity √(g/L) but inside ω is √(k/m) where do i find k constant in this question?
