A thin metal rod of mass 1.2 kg and length 0.8 m is at rest in outer space, near a space station (see figure below). A tiny meteorite with mass 0.07 kg traveling at a high speed of 195 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 θ_{i} = 26° and θ_{f} = 82°.

(a) Afterward, what is the velocity of the center of the rod? (Express your answer in vector form.)

v_{CM} = m/s

(b) Afterward, what is the angular velocity ω of the rod? (Express your answer in vector form.)

ω = rad/s

(c) What is the increase in internal energy of the objects?

J
