Question

Given d = 1 2 at2, solve for a. A) a = t2 2d B) a = 2d t2 C) a = d - 1 2 t2 D) a = 1 2 t2 - d

Answer 1

Given expression:
`d=(1)/(2) at^2`.

We need to solve it for a.

First we need to get rid 2 from denominator.

In order to get rid 2 from denominator, we need to multiply both sides by 2.

Multiplying both sides by 2, we get

`2* d=2* (1)/(2) at^2`

`2d = at^2`

Now, dividing both sides by t^2, we get

`(2d)/(a^2) = (at^2)/(a^2)`

`a=(2d)/(a^2)`.

Therefore, correct option is B option.

`a=(2d)/(a^2)`
