Which Direction Does Angular Momentum Point When Traveling North?

[baseballer]

Homework Statement

A) You travel north down a road in a car at constant velocity. In which direction (N, S, E, W, up, down) does the angular momentum vector point for one of the tires.

B) Same situation. If you slam on the brakes in which direction does the angular acceleration vector point for one of the tires. (N, S, E, W, up, down)

Homework Equations

L = r x p

The Attempt at a Solution

For A, I think it's East because of the right hand rule. My fingers would be curling forward and my thumb would be pointing to the Left.

For B, I'm not sure. I guess it would be West just because acceleration would be negative and in the opposite direction of A.

You think left is East?

Sorry about that. I meant West for A and East for B

Sounds good to me.
