In the figure below, the bar has moment of inertia 0.4 Kgm^2 and is spinning clockwise, around an axis passing through the depicted point and perpendicular to the plane of the page, with angular speed of 10 1/s (or 10 rad/s). The 4 N depicted force, generates a constant torque (which slows down the bar rotation) for 2 seconds. Calculate the magnitude of the applied torque. Calculate the angular speed of the torque at t = 2 s.
3. An object has a moment of inertia equal to 6.0 kg.m. If the object's angular velocity increasing at the rate of 2.0 rad/s, what is the net torque acting on the object?

Moment of Inertia/Conservation of Angular Momentum 10) Consider a cat in free-fall, as shown above (assume no external torques act upon it). As it falls, the cat has an initial angular velocity of: o 1.6 rad/s, and an initial moment of inertia of: In=7.5x 10 kgm. If the cat extends its legs so that its moment of inertia increases to I nal12.0x10 kgm, what would be the cat's final angular velocity?
