Another diver leaves a platform with an angular momentum (H) of 1500 kg m ² /sec. Her angular velocity (@) is initially 5 rad/sec. If she needs to increase her angular velocity to 6 rad/sec, what should she do? O Tuck her body into a tighter ball, decreasing her moment if inertia (I) to 250 kg m2. O Open up her body into a more extended position, decreasing her moment if inertia (1) to 250 kg m2. O Open up her body into a more extended position, increasing her moment if inertia (I) to 350 kg m2. O Tuck her body into a tighter ball, increasing her moment if inertia (I) to 350 kg m2.

Could you help with sections B and C?

Curl of a rotation field Compute the curl of the rotation fieldF = a x r, where a = ⟨2, -1, 1⟩ and r = ⟨x, y, z⟩(see figure). What are thedirection and the magnitude of the curl?
