An object initially at rest experiences an acceleration of 5 m/s2. How much time will it take it to achieve a velocity of 40 m/s?

8 s

Explanation:

Given:

v₀ = 0 m/s

v = 40 m/s

a = 5 m/s²

Find: t

v = at + v₀

40 m/s = (5 m/s²) t + 0 m/s

t = 8 s

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

i can do 50 in a row ( but i get so tired after that)
