Question

An aeroplane is flying horizontally with a velocity of 600 km/h at a height of 1960 m. When it is vertically at a point A on the ground, a bomb is released from it. The bomb strikes the ground at point B. The distance AB is

• A. 1200 m
• B. 0.33 km
• C. 3.33 km
• D. 33 km

Answer 1

Answer: (C)

3.33 km

Answer 2

Horizontal displacement of the bomb

AB = Horizontal velocity × time available

$AB = u \times \sqrt{\frac{2h}{g}} = 600 \times \frac{5}{18} \times \sqrt{\frac{2 \times 1960}{9.8}} = 3.33Km.$
