Homework Statement
Hiya boys,
Sorry i don't 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
