Simple Pendulum Centripetal Acceleration

  • Thread starter robwashere
  • Start date
1. The problem statement, all variables and given/known data

2. Relevant equations
Im guessing: Centripetal Acceleration = v^2/r
PE = mgh
KE = .5mv^2

3. The attempt at a solution
I tried to convert the givens into velocity by using .5mv^2, but that does not work.

Hint: Apply Newton's 2nd law.
