The velocity of a diver just before hitting the water is -7.7 m/s, where the minus sign indicates that her motion is directly downward. what is her displacement during the last 0.82 s of the dive?

The velocity of a diver just before hitting the water is -7.7 m/s ( i.e final velocity ).

Therefore velocity of diver before 0.82 s,

.

Now the displacement  during the last 0.82 s of the dive, from the vertical motion,

Thus, the displacement is 3.0 m in downward.

muscle endurance

explanation:

i can do 50 in a row ( but i get so tired after that)
