Two Objects of Mass M₁ = 2m and M₂ =

question 28

Multiple Choice

Two objects of mass m₁ = 2m and m₂ = m move around a rotation axis A in parallel circles of radii r₁ = r and r₂ = 2r with equal tangential speeds. As they rotate, forces of equal magnitude are applied opposite to their velocities to stop them. Which statement is correct?

• A) m₂ will stop first because it has the larger initial angular velocity.
• B) m₁ will stop first because it has the smaller radius.
• C) m₂ will stop first because the torque on it is greater.
• D) m₁ will stop first because it has the smaller moment of inertia.
• E) Both objects will stop at the same time because the angular accelerations are equal.
