Dancers experience large forces associated with the jumps they make. for example, when a dancer lands after a vertical jump, the force exerted on the head by the neck must exceed the head’s weight by enough to cause the head to slow down and come to rest. the head is about 9.4% of a typical person’s mass. video analysis of a 67 kg dancer landing after a vertical jump shows that her head slows down from 4.2 m/s to rest in a time of 0.19 s.
