Non uniform circular acceleration

[hav0c]

Homework Statement

A car is moving with a speed of 30m/s on a circular path of radius 500m. It's speed is increasing at a rate of 2m/s². What is the acceleration of the car.

Homework Equations

That is my problem.

The Attempt at a Solution

Well i know equations for uniform circular motion but this is just beyond me.

Hint: You are given the tangential component of the acceleration. What's the radial component?

 

[CWatters]

An object is accelerating if it's speed or direction is changing. Your car appears to be subject to two acceleration vectors. You know how to add two vectors?

Edit: Deleted a bit of this reply as otherwise too easy.

oh
that was surprisingly easy
i was messing up with vector addition
thanks anyways.

Just to play the devil...

What about gravity? Is it really three vectors :-)

Why do you think that would matter? (It's on a circular path.)
