QUESTION: A balloon is moving upwards with velocity of 10m/s. it releases a stone which comes down to the ground in 11s. find the height of the balloon when stone is dropped?
ANSWER
A ballon moving upwards with constant velocity 10m/s . if we release the stone from ballon , then, initial speed of stone = 10m/sec .
now,
initial speed = 10m/sec
time = 11sec
let H is the height of ballon when stone is dropped .
use kinematics equation ,
S = Ut + 1/2at²
-H = 10 × 11 - 1/2 × 10 × (11)²
= 110 - 5× 121
= 110 - 605
= -495 m
- H = -495 m
hence, H = 495 m
so, height of ballon is 495m when stone is dropped .
