Question

The equation f = v + at represents the final velocity of an object, f, with an initial velocity, v, and an acceleration rate, a, over time, t. Which is an equivalent equation solved for a?

Answer 1

Answer: A f-v/t=a

Explanation:

Answer 2

Let

f------> the final velocity of an object

v------> an initial velocity

a-----> an acceleration rate

t------> the time

we have

`f = v + at`

Solve for a-------> that means clear variable a

Subtract v both sides

`f-v = v + at-v`

`f-v = at`

Divide by t both sides

`(f-v)/t = at/t`

`(f-v)/t = a`

so

`a=(f-v)/t`

therefore

the answer is

`a=(f-v)/t`
