44. belly-flop bernie dives from atop a tall flagpole into a swimming pool below. his potential energy at the top is 10,000 j (relative to the surface of the pool). what is his kinetic energy when his potential energy is reduced to 1000 j

9000 J

Explanation:

Potential energy at the top = 10,000 J

Final potential energy = 1000 J

use the conservation of mechanical energy

Potential energy at top + kinetic energy at top = potential energy at a point + kinetic energy at that point.

10000 + 0 = 1000 + kinetic energy

kinetic energy = 10000 - 1000

kinetic energy = 9000 J

Thus, the kinetic energy is 9000 J.

the arctic is a region of the planet, north of the arctic circle, and includes the arctic ocean, greenland, baffin island, other smaller northern islands, and the far northern parts of europe, russia (siberia), alaska and canada.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
