Question

# An aeroplane is flying horizontally with a velocity of $$600 km/h$$ and 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
1200m
B
0.33km
C
3.33km
D
33km

Solution

## The correct option is C $$3.33 km$$The velocity with which the bomb is released is $$600km/h(horizontal)$$.Vertical velocity of the bomb is $$zero$$.So.distance $$AB=600\dfrac{5}{18}*t$$        $$t$$ is the time taken by the bomb to reach the ground.$$1960=g\dfrac{{t}^{2}}{2}$$which gives $$AB$$ equal to $$3.3.km$$.Physics
