Araindrop drops from a window ledge of a building. the window ledge is 80 feet above the ground. how long does it take before the drop passes by another window ledge that is 16 feet above the ground?

It takes 2 seconds before the drop passes through another window ledge that is 16 ft above the ground.

Step-by-step explanation:

The formula to find time is

Here the drop falls from a window which at a height of 80 ft.

Hence the initial velocity = 0 = u

Now when it passes through a widow at a height of 16 ft, it has covered a distance of = 80-16 = 64 ft = d

It is falling under the gravity so its acceleration = g = 9.8 m/s² = 32 ft /s²

Substituting the values in the formula we get

Dividing both sides by 16 we get

Taking square root on both sides we get

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
