Here, u $$=$$ $$720$$ km $$h-1$$            $$=$$ $$720$$ ×$$518$$ $$ms-1$$ $$=$$ $$200$$ $$ms-1H$$ $$=$$ $$1.5km$$ $$=$$ $$1.5$$ × $$1000$$ m $$=$$ $$1500$$ mTime taken by the bomb to attack the targett $$=$$ $$2Hg$$ $$=$$ $$2$$×$$1500$$ $$m10$$ $$ms-2$$ $$=$$ $$300s$$ $$=$$ $$103sR$$ $$=$$ u × t $$=$$ $$200$$ $$ms-1$$ × $$103s$$ $$=$$ $$20003mFrom$$ figure,Angle of sight (w$$.r.t $$horizontal) α $$=$$ $$tan$$$$-1(HR)$$α $$=$$ $$tan$$$$-1(150020003)$$ $$=$$ $$tan$$$$-1(343)$$ $$=$$ $$tan$$$$-1(34)$$

A fighter plane is flying horizontally at an altitude of 1.5 km with speed 720 km $h^{- 1}$ . At what angle of sight (w.r.t. horizontal) when the target is seen, should the pilot drop the bomb in order to attack the target? (Take g = 10 ${ms}^{- 2}$ )
