(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

David is driving a steady 30.0 m/s when he passes Tina, who is sitting in her car at rest. Tina begins to accelerate at a steady 2.0 m/s^2 at the instant when David passes.

a. How far does Tina drive before passing David?

b. What is her speed as she passes him?

Velocity init. for Tina= 0 m/s

Velocity final for Tina= 30.0 m/s

Tina's acceleration= 2.0 m/s^2

2. Relevant equations

V_{2}^{2}= V_{1}^{2}+ 2a(change in time)

3. The attempt at a solution

I've plugged these values into this equation to get 225m. I'm not sure what I'm doing it correct, though. It does not sound correct to me. My other idea was to graph their velocity at the moment David passes Tina and figure the answers out graphically. Is there a way to do this algebraically?
