Answer:
3117.914 m tall mountain
Explanation:
Chocolate bar gave him 2.2 Mega Joules energy
Gravitational Potential energy = mgh
now, if he store that energy entirely as gravitational potential energy then
mgh = 2.2×10^6
⇒ 72 × 9.8 × h = 2.2×10^6
⇒h = (2.2×10^6)/(72×9.8) = 3117.914 m
The so-called "terminal velocity" is the fastest that something can fall
through a fluid. Even though there's a constant force pulling it through,
the friction or resistance of plowing through the surrounding substance
gets bigger as the speed grows, so there's some speed where the resistance
is equal to the pulling force, and then the falling object can't go any faster.
A few examples:
-- the terminal velocity of a sky-diver falling through air,
-- the terminal velocity of a pecan falling through honey,
-- the terminal velocity of a stone falling through water.
It's not possible to say that "the terminal velocity is ----- miles per hour".
If any of these things changes, then the terminal velocity changes too:
-- weight of the falling object
-- shape of the object
-- surface texture (smoothness) of the object
-- density of the surrounding fluid
-- viscosity of the surrounding fluid .

The following are the guidelines for creating ray diagrams for the generation of an image by a concave mirror:
Rule 1: If the incident ray is parallel to the major axis, the reflected ray will pass through the concave mirror's focus.
The reflected ray is parallel to the principal axis if the incident ray passes through the focus of the concave mirror.
Rule 3: If the incident ray passes through the concave mirror's center of curvature, the reflected ray follows the same path.
Hope this helps!
