Question

an aeroplane is flying horizontally with a velocity 720km/h at a height of 2000m.when it is verticallly 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.1km b.2km c.3km d.4km

Answer 1

Answer:

y=ut+1/2gt^2

2000=+1/2×10×t^2

t=20

a=720-0/20

a=36

(720)^2-0=2×36×s

s=7200m
