A jet aeroplane is flying at a constant height of 2 km with a speed `360 kmh^(-1)` above the ground towards a target and releases a bomb. After how much time it will hit the target and what will be the horizontal distance of the aeroplane from the target so that the bomb should hit the target ? (Take `g = 10 ms^(-2))`
A. 10s, 1km
B. 20 s, 2km
C. 30s, 3km
D. 40s, 4km
