Aleonysh [2.5K]

<u>Answer</u>:

It takes 5 seconds for the sandbag to hit the ground

<u>Explanation</u>:

Given:

Height at which the sand bag is released from the hot air balloon= -400 f t

To find:

Time taken for the sandbag to hit the ground, t =?  

Solution:

The initial height =s

Initially the height will be 0

Hences=0

the falling object model equation  

h=-16 t^{2}+s

Substituting the values we get,

h=-16 t^{2}+s

400=16 t^{2}

t^{2}=\frac{400}{16}

t^{2}=25

t=\sqrt{25}

t=5 \text { seconds }

Result:

Thus it takes 5 seconds for the sandbag to hit the ground
