Question

Please help!!!!!!!!!!

Answer 1

1.

`(1)/(2)at^2=vt-d`

2.

`at^2=2(vt-d)`

3.

`a=(2(vt-d))/(t^2).`

Explanation:

First, express from the formula
`d=vt-(1)/(2)at^2` the term
`(1)/(2)at^2:`

`(1)/(2)at^2=vt-d`

Now multiply this equation by 2:

`at^2=2(vt-d)`

and divide it by
`t^2:`

`a=(2(vt-d))/(t^2).`
