Answer: 565.6m
Explanation:
Given height is 1000m
Speed of aeroplane is 144km/h i.e. 144×5/18 = 40m/s.
You can use the following formula to calculate distance for such type of questions :
D= u√2H/g
Where D is distance, u us initial velocity, H is height and g is acceleration due to gravity.
Taking g = 10m/s²
D= 40√2×1000/10
D= 40√2000/10
D= 40√200
D= 40×14.14
D= 565.6m
Hope it helped....
Cheers..!!
