Explanation:
Detailed explanation-1: -AB = u × √2hg = 600× 518×√2×19609.8 = 3.33 km. Q.
Detailed explanation-2: -Hence, the vertical distance between the aeroplanes at that instant is 1690.599m.
Detailed explanation-3: -Due to air resistance, it’s horizontal velocity will decrease so it will fall behind the aero plane.
