A simple pendulum of length L having a bob of mass m is deflected from its rest position by an angle $θ$ and released (figure) The string hits a peg which is fixed at a distance x below the point of suspension and the bob starts going in a circle centred at the peg. If the pendulum is released with $θ = 90^{\circ}$ and x = $\frac{L}{2}$ find the maximum height reached by the bob above its lowest position before the string becomes slack.
