Given data:
* The distance traveled is 346 m.
Solution:
Let m be the mass of the body.
Then, the gravitational potential energy of the body on reaching the top of the tower is,
where g is the acceleration due to gravity, and h is the height of the tower,
As mg is the weight of the body.
Substituting the known value,
where w is the weight of the body,
When a person walks to the certain height, the internal energy of the person's body is converted into the gravitational potential energy.
