Answer:
2450 J
Explanation:
Given that,
A 50Kg girl jumps off a 5-meter-high diving board.
We need to find the kinetic energy of the girl before she hits the water. At this point the kinetic energy becomes equal to the potential energy such that,
[tex]K=mgh\\\\K=50\times 9.8\times 5\\\\K=2450\ J[/tex]
So, her kinetic energy right before she hits the water is equal to 2450 J.
