APFIVE Angular Momentum in an Inelastic Collision
Two asteroids of equal mass collide and stick together in space far from other objects. Before the collision, one asteroid was rotating clockwise at angular velocity ω₀ while the other was not rotating. After the collision, the combined object will:
A
Rotate at an angular velocity greater than ω₀/2
B
Not rotate at all
C
Rotate at exactly ω₀/2
D
Rotate at an angular velocity less than ω₀/2
