APFIVE Conservation of Angular Momentum in a Collision
A solid disk with moment of inertia I₁ and angular velocity ω₁ collides with a stationary ring with moment of inertia I₂. After the collision, they stick together and rotate with angular velocity ω₃. Which expression correctly represents this interaction?
A
I₁ω₁² = (I₁ + I₂)ω₃²
B
I₁ω₁ = I₁ω₃ + I₂ω₃
C
I₁ω₁² + I₂ω₂² = (I₁ + I₂)ω₃²
D
I₁ω₁ = (I₁ + I₂)ω₃
