Homework Statement
The question is in part 3 (image). Basically I used the formula for Period, T, of a pendulum of length L with freefall acceleration g. I got 8.52, but I had to further divide this number by 4 to get the time the person must hang on in order to drop into the water at the greatest possible instance from the edge. Why does it need to be divided by 4? I know that leaving the answer to be equal to T is wrong because you'd be back to your original position. But why divide by 4?
