As we know that total work done by a force is given by
so it is product of force and displacement along same direction
as we can write it as
so it must be the product of force and displacement in same directions so correct answer must be
<u>b. is parallel to the displacement of the object</u>
Answer:
The woman's average velocity during the trip is 36.2 miles/hour.
Explanation:
Velocity can be define as the displacement of an object per time. It is a vector quantity, and measured in m/s.
i.e velocity =
From the given question,
Displacement =
=
=
= 425
The displacement of woman is 425 miles.
velocity =
= 36.1702 miles/hour
The woman's average velocity during the trip is 36.2 miles/hour.
