# Motion equation

## Homework Statement

How do you transpose s=ut + 1/2at^2 for the a?

s=ut + 1/2at^2

## The Attempt at a Solution

s=ut + 1/2at^2
s-ut=1/2at^2
a=s-ut/0.5t^2

This is so wrong, could someone help me?

## The Attempt at a Solution

Either way did you mean $$a=\frac{s-ut}{0.5 t^2}=2 \frac{s-ut}{t^2}$$?
