Achampion athlete can produce one horsepower (746 w) for a short period of time. if a 70-kg athlete were to bicycle to the summit of a 500-m high mountain while expending power at this rate, she would have used at least j of energy

343000 J

Explanation:

P = Power produced by champion = 756 W

h = height gained by the athlete = 500 m

m = mass of the athlete = 70 kg

E = Least amount of energy

Least amount of energy is same as the potential energy gained , So using conservation of energy

Energy spent by athlete = Gravitational potential energy

E = (70) (9.8) (500)

E = 343000 J

a women have faced negative attitudes in some areas , but other

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.
