Homework Statement
A simple pendulum of length 1m with bob mass 125g is pulled 15 degrees to the right and released at t=0.What are the phase constant and amplitude?
Homework Equations
θ(t)=Acos(ζt+phi) ---> my teacher gave us a weird symbol that I've never seen before, it has always been ω instead of ζ on classwork and such.
The Attempt at a Solution
I am just completely lost with how to even start this. My teacher doesn't explain anything, he basically gives us in-class problems that have nothing to do with the homework he assigns. Can someone explain how amplitude and phase constant can be found?
