A shell is fired from a fixed artillery gun with an initial speed $\displaystyle u$ such that it hits the target on the ground at a distance R from it. If $\displaystyle \mathrm{t}_1$ and $\displaystyle \mathrm{t}_2$ are the values of the time taken by it to hit the target in two possible ways, the product $\displaystyle \mathrm{t}_1 \mathrm{t}_2$ is :
