# Angular velocity

[SOLVED] Angular velocity

## Homework Statement

The angular acceleration of a flywheel of a generator is given by

a(t) = 6bt - 12ct2

What is the angular velocity at t when the initial velocity is w0?

## The Attempt at a Solution

w = w0 + at = w0 + 6bt2 - 12ct3

This is wrong according to my book. Can't I use the same equations for angular motion as for linear motion?

The equation you have written is for solving angular velocity when the angular acceleration is constant.
