Problem

A medieval catapult is designed to launch a stone to land on a castle wall

15\,\text{m}

high at a horizontal distance of

60\,\text{m}

. It is found that there are two possible launch angles for a fixed launch speed of

30\,\text{m/s}

to hit this specific target point. Find the ratio of the time of flight for the high trajectory (larger angle) to the time of flight for the low trajectory. (Take

g = 10\,\text{m/s}^{2}

)
