Can the diver of Fig. 8–29 do a somers0nvjsetju skw7q 3/ ood( (w/-ault without having any init -gg y8c11: st/ridw.h-ttx usial rotation when she leave1 8.ut- i-w1rs/htgc dx:ystg s the board?

参考答案:

In order to do a somersault, the diver needs some initial angular momentum when she leaves the diving board, because angular momentum will be conserved during the free-fall motion of the dive.  She cannot exert a torque on herself in isolation, and so if there is no angular momentum initially, there will be no rotation during the rest of the dive.
