Answer :
Final answer:
To calculate the average power required by the runner, we can use the formula Power = Work / Time. Substituting the given values, we can calculate the average power.
Explanation:
To calculate the average power required by the runner, we can use the formula:
Power = Work / Time
The work done by the runner can be calculated as the change in potential energy:
Work = mgh
where m is the mass of the runner, g is the acceleration due to gravity, and h is the vertical height of the hill.
Plugging in the values into the formula, we have:
Power = (mass) x (gravity) x (height) / time
Substituting the given values, we have:
Power = (85 kg) x (9.8 m/s^2) x (29.0 m) / 103 s
Calculating this expression will give us the average power required by the runner.
