A person is hanging motionless from a vertical rope over a swimming pool. She let it go of the rope and drops straight down. After letting go, is it possible for her to curl into a ball and start spinning? Give a brief justification for your answer.
It is possible you rotate or make turns in the air.
Remember, if there is no resistance, the angular momentum is conserved.
when she is falling down straight, there is no angular velocity, so the angular momentum is 0.
therefore, the angular momentum is always 0 at time ...
It finds the possibilibyt of the person to curl to a ball and start spinning after dropping down from a vertical rope.
