## Homework Statement

Hiya boys,

Sorry i dont know how to proceed with this problem can anyone help me solve these two questions?

In preparation for building a space station, an astronaut removes a self-telescoping uniform rod from the cargo bay and releases it, not noticing that he gave it an angular speed of 0.0500 radians per second. The pole is 3.00 meters long. A catch slips, and the pole spring retracts it into a shorter 1.50 meter long uniform pole about a minute after the astronaut releases it.

Find the angular speed after the catch slips.

## Homework Equations

I = mr^2/12 or mr^2/3

ω = v/r

## The Attempt at a Solution

Iinitial = Ifinal

m (3^2)/12 = m (1.5^2)/12

m= do i need this?

(0.05)(x) = ω
