Quizplus · Accepted Answer

The angular momentum of an object is given by the formula L = Iω, where I is the moment of inertia and ω is the angular velocity. The moment of inertia of a point mass is given by the formula I = mr^2, where m is the mass and r is the distance from the axis of rotation. The angular velocity is given by the formula ω = v/r, where v is the linear velocity. Substituting these formulas into the formula for angular momentum, we get L = mvr. Plugging in the given values, we get L = (30.0 kg)(2.70 m/s)(50.0 m) = 4050 N.
