Adiver in midair has an angular velocity of 6.0 rad/s and a moment of inertia of 1.2 kg·m2. he then pulls is arms and legs into a tuck position and his angular velocity increases to 12 rad/s. the net external torque acting on the diver is zero. what is his moment of inertia in the tuck position?

What is a costume plot? why is it important to a film or theater production?

The force it would take to accelerate an 900-kg car at the rate of 6m/s2
