A chocolate bar has nutritional energy content of 100KJ. If an 50kg mountain climber eats this chocolate bar and converts it all to potential energy.


What altitude(height) can she climb on a mountain using this energy? Consider g=10m/s^2


PLEASEEEE HELPPPPPP

Respuesta :

Answer:

h = 200 m

Explanation:

Given that,

A chocolate bar has a nutritional energy content of 100 kJ.

Mass of a mountain climber, m = 50 kg

He eats this chocolate bar and converts it all to potential energy. Using the conservation of energy.

[tex]E=mgh\\\\h=\dfrac{E}{mg}\\\\h=\dfrac{100\times 10^3}{50\times 10}\\\\h=200\ m[/tex]

So, she can climb from a height of 200 m.
