Find the potential energy associated with a 61-kg hiker atop New Hampshire's Mount Washington, 1900 m above sea level. Take the zero of potential energy at sea level.

Respuesta :

Answer:

The potential energy of the hiker is [tex]1.13\times 10^6\ J[/tex].

Explanation:

Given that,

Mass of the hiker, m = 61 kg

Height above sea level, h = 1900 m

We need to find the potential energy associated with a 61-kg hiker atop New Hampshire's Mount Washington. The potential energy is given by :

[tex]E=mgh[/tex]

g is the acceleration due to gravity

[tex]E=61\ kg\times 9.8\ m/s^2\times 1900\ m\\\\E=1.13\times 10^6\ J[/tex]

So, the potential energy of the hiker is [tex]1.13\times 10^6\ J[/tex]. Hence, this is the required solution.
