## Homework Equations

vf=vi+axt

## The Attempt at a Solution

For part A.[/B]

1. Since ax=0.5m/s^2,

2. .5(m/s^2)/9m=.055555551/s^2

3. Invert: (.055555551/s^2)^-1=18s^2

4. sqrt: 18s^2=4.24 s

5. Plug in: Get 2.1 m/s

The answer is supposed to be 3.00 m/s. Is there suppose to be a different way of setting it up.
