My Notes
A thin metal rod of mass 1.4 kg and length 0.9 m is at rest in outer space, near a space station (see figure below). A tiny meteorite with mass
0.05 kg traveling at a high speed of 225 m/s strikes the rod a distance 0.2 m from the center and bounces off with speed 60 m/s as shown in the
diagram. The magnitudes of the initial and final angles to the x axis of the small mass's velocity are $\theta_i = 26^\circ$ and $\theta_f = 82^\circ$.
(a) Afterward, what is the velocity of the center of the rod? (Express your answer in vector form.)
$\vec{v}_{CM} = $ 13.16
$\times$ m/s
(b) Afterward, what is the angular velocity $\vec{\omega}$ of the rod? (Express your answer in vector form.)
$\vec{\omega} = $
rad/s
(c) What is the increase in internal energy of the objects?
