Answer:
The displacement is zero miles
Explanation:
The displacement of an object that moves from point A to point B is defined as
Where d is the displacement of the object. The displacement does not depend on the trajectory of the object. It only depends on the linear distance between the end point and the starting point.
In this case we know that the person walks from home to work and then walks from work to home. Therefore, the total displacement is the linear distance between the point where its journey begins and the point where the route ends.
The tour begins on the front porch of your house and ends on the front porch of your house (when you return from work). If we call A to the front porch of the house then the displacement is:
The displacement is zero miles, since the person finishes the journey just where it started (front porch)
The potential energy of the body is "200 Joule".
According to the question,
Mass,
- m = 10 kg
Height,
- h = 200 cm
or,
= 2 m
- g = 10 m/s⁻¹
As we know,
→ The potential energy will be:
=
By putting the given values, we get
=
=
Thus the above answer is right.
