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.
Tuck her body into a tighter ball, increasing her moment if inertia (I) to 350 kg m2.

Step 1

Given initial angular momentum Li=1500kgm2/sec

And initial angular velocity ωi=5rad/s

And final angular velocity is ωf=6rad/s
