An aeroplane is flying horizontally with a velocity of 216 k m h - 1 and at a height of 1960 m. When it is vertically above a point A on the ground, a bomb is released from it. The bomb strikes the ground at point B. The distance AB is (ignoring air resistance) (given g = 9 .8 m s - 2 )

Question

An aeroplane is flying horizontally with a velocity of 216 k m h - 1 and at a height of 1960 m. When it is vertically above a point A on the ground, a bomb is released from it. The bomb strikes the ground at point B. The distance AB is (ignoring air resistance) (given g = 9 .8 m s - 2 ), 1200 m, 0.33 km, 3.33 km, 33 km

MARKS App · Accepted Answer

Horizontal velocity of aeroplane, in m/s u = 216 × 1000 60 × 100 = 60 m s - 1 Time of flight, T = 2 h g = 2 × 1960 9.8 = 20 s Horizontal range, A B = u T = 60 × 20 = 1200 m
