Answer:

<h2>100, -50, 25, -12.5, 6.25, -3.125, 1.5625, -0.78125</h2>

Step-by-step explanation:

Each term is being multiplied by <u>-0.5</u>

How did I know?

Divide the second term by the first.

-50 divided by 100 = -1/2

Find the last four terms.

-12.5 x -1/2 =<em> </em><u><em>6.25</em></u>

6.25 x -1/2 = <u><em>-3.125</em></u>

-3.125 x -1/2 = <u>1.5625</u>

1.5625 x -1/2 =<em><u> -0.78125</u></em>

A raindrop was 24 meters above the ground, falling straight down at a constant velocity. It took the raindrop 3 seconds to fall
lina2011 [118]

Answer:

4 m/s downwards

Step-by-step explanation:

Velocity is given by dividing the distance by time taken to cover the diatance. Therefore, expressed as v=d/t

The distance is given as 24 m but the time given covers only half the distance. Therefore, the distance is 0.5*21=12 m

Time taken is given as 3 s

Substituting 12 m for d and 3 s for t then

V=12/3= 4 m/s

Velocity must have direction component hence velocity is 4 m/s downwards
