flywheel angular deceleration

I cant answer this. My formula w^2=wo^2+2a doesnt work  :'(

A flywheel has a constant angular deceleration of 2.5 rad/sec^2.

1. Find the angle through which the flywheel turns as it comes to rest from an angular speed of 117 rad/sec.
2. Find the time required for the flywheel to come to rest.


please help need fast

Google is a cool thing.

Also apparently you are missing the theta after 2a in your formula.

w = 0 rad/sec
wo = 117 rad/sec
a = -2.5 rad/sec^2
So solve for theta.
There's another simple equation you can use to answer part 2. You have w, wo, and a, and you need to find t. I'm sure you can find the formula in your book somewhere. If not, it is analogous to one of your 5 basic kinematic equations, simply replacing linear measurements for corresponding angular ones, so if you can't find it, you should be able to figure it out.

Also this isn't a discussion. :(

Oh god, there's no such thing as deceleration. Just accelerating in the opposite direction. My Physics teacher would busload if he saw dis :D
