Lesson: Angular Impulse High School Physics

Which of the following quantities has the same units as angular impulse?

An object is rotating with an angular velocity of 44 rad/s. A torque of 0.23 N⋅m is applied to the object, which brings it to a stop in 135 s. What is the moment of inertia of the object? Give your answer to 2 significant figures.

An object with a moment of inertia of 3.2 kg⋅m² around its axis of rotation initially has an angular velocity of 5.0 rad/s. A torque is applied to the object for 22 s, after which time it has an angular velocity of 48 rad/s. What is the magnitude of the torque applied to the object? Give your answer to 2 significant figures.
