8. An object that is traveling 50m/s slows down with an acceleration rate of -3.5m/s/s. This took place over a period of 4s.
What was the objects final velocity? *

36 m/s

Explanation:

Given:

v₀ = 50 m/s

a = -3.5 m/s²

t = 4 s

Find: v

v = at + v₀

v = (-3.5 m/s²) (4 s) + 50 m/s

v = 36 m/s

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

he . if i may ask what i your question exactly?
