A) 1200m
B) 0.33 km
C) 3.33km
D) 33 km.
Correct Answer: A
Solution :
: Horizontal velocity of aeroplane, \[u=\frac{216\times 1000}{60\times 60}=60\,m/s\] Time of flight, \[T=\sqrt{\frac{2s}{g}}=\sqrt{\frac{2\times 1960}{9.8}}=20\,s\] Horizontal range,\[=AB=nT\] \[=60\times 20=1200m\].You need to login to perform this action.
