Answer:
Diver hits the water with kinetic energy of 5000 J
Step-by-step explanation:
We have given weight of the diver F = 500 N
Diver steps off a diving board which is 10 m above the water
So work don by diver

Now according to energy theorem work done is equal to kinetic energy
So kinetic energy will be equal to 5000 J
So diver hits the water with kinetic energy of 5000 J
