PLZ HELP ME ITS MY LAST QUESTION I GOT LIKE 6 MIN LEFT A 77kg diver jumps from a 8.18m high diving platform. Why is the speed in m/s of the diver right before she hits the water?

12.7m/s

Explanation:

Given parameters:

Mass of the diver  = 77kg

Height  = 8.18m

Unknown:

Speed of the diver before hitting the water = ?

Solution:

The speed of the diver before hitting the water is the final velocity.

       To solve this problem, we use the expression below;

       v² = u²  + 2gH

v is the final velocity

u is the initial velocity

g is the acceleration due to gravity

H is the height

  Now insert the parameters and solve;

 v²   = 0²   + 2 x 9.8 x 8.18

 v²   = 160.328

  v  = 12.7m/s

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
