Question

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

Answer 1

h = 200 m

Step-by-step 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.

`E=mgh\\\\h=(E)/(mg)\\\\h=(100* 10^3)/(50* 10)\\\\h=200\ m`

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