Height at which the sand bag is released from the hot air balloon
To find:
Time taken for the sandbag to hit the ground, t =?
Solution:
The initial height =s
Initially the height will be 0
Hence
the falling object model equation
Substituting the values we get,
Result:
Thus it takes 5 seconds for the sandbag to hit the ground
Answer:
c=2πr
