An aeroplane moving horizontally with a speed of `720 km//h` drops a food pocket, while flying at a height of 396.9 m . the time taken by a food pocket to reach the ground and its horizontal range is (Take `g = 9.8 m//sec`)

A

3 sec and 2000 m

B

5 sec and 500 m

C

8 sec and 1500 m

D

9 sec and 1800 m

Text Solution

Verified by Experts

The correct Answer is:
D
Time (t) `=sqrt((2h)/g) = sqrt((2 xx 396.9)/9.8) = 9 sec`
Range (R ) = `ut = 720 xx 5/18 xx 9 = 1800 m`
