A sandbag is released from a hot air balloon that is 400ft above the ground. Using the falling object model, h = –16t2 + s, wher

Aleonysh [2.5K]

Answer:

It takes 5 seconds for the sandbag to hit the ground

Explanation:

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

Hence $s=0$

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
