Question

V=vo+at;find a if v = 20, vo = 30, t =5.​

Answer 1

Step-by-step explanation:

$V = V _{0} + at \\ 20 = 30 + a \times 5 \\ 5a = 20 - 30 \\ 5a = - 10 \\ \\ a = - \frac{10}{5} \\ \\ a = - 2$

Answer 2

Answer:

-2 = a

Step-by-step explanation:

v = vo + at

20 = 30 + a5

now get the numbers and the variable on different sides

30 + a5 - 30 = a5

20 - 30 = -10

-10 = a5

now im going to divide each side by 5

a5 / 5 = a

-10 / 5 = -2

-2 = a
