## Homework Statement

Question Details:

A 10 kg engine is rotating at the rate of 20 rad/sec about a point on a wire 3 meters in length with a working tensile strength of 1.8*106 N. The engine is fired and produces an acceleration of 1 rad/sec2. What's the maximum possible ω (angular velocity) (in other words: 1)

**whats's the fastest ω which doesn't break the wire?**) 2)

**How long should the engine be fired to reach the maximum possible ω?**3)

**How far will the engine travel in meters while it's accelerating to the maximum possible ω?**

## Homework Equations

## The Attempt at a Solution

I believe it's right, however this is only #1. Need help on #2 and #3.

Thanks!
