Question

An aeroplane is flying horizontally with a velocity of 600 at a height of 1960

Answer 1

Initial horizontal velocity , u= 699 km / h= 166.6m/s.Initial velocity = 0m/s

Let the time taken to reach the ground be t sec. Vertical distance covered h= 1960

h=1/2gt^2

t= root 2h/ g

Horizontal range AB= ut

=> u× root 2h/g

=> 166.67root 2×1960/9.8

=> 333.4m

=> 3.3km

Hope it will help you!☺
