Energy conservation indicates that M g L (1-cos A) + (1/2)M V^2 = M g L (1-cos Amax) at any angle location A. M cancels out. Your Amax angle is 27.5 degrees, so: g L (1 - cosA) + V^2/2 = 0.11299 gL Use that equation to solve for V at any angle A

Since mechanical energy is the sum of kinetic and potential energy, the answer to your question is zero. E(mech) = E(pot) + E(kin) E(kin) = E(mech)- E(pot)= 0, in this case
