The work done by Sarah is 3000 J
Explanation:
The work done by Sarah in climbing the set of stairs up is equal to its change in gravitational potential energy, and it is given by:
where:
F is Sarah's weight
d is the vertical distance covered by Sarah
In this problem, we have:
F = 500 N is Sarah's weight
d = 6 m is the vertical distance covered by Sarah
Substituting, we find the work done:

For the speed of an object you need to know how far it is travelling in a given time. Typically you do this by measuring the time it takes for the object to travel a set distance.
<span>For the velocity of an object you also need to know the direction the object is travelling in.

The reference point is wherever you want it to be. If you define it
as the tip of the nose of one of the people, that's fine. Alternately,
it could be one of the claws on the dog across the street, or a leaf
on the tree that's directly over the people.
Since you're planning on describing the motion of the car, you
probably don't want to pick the car itself as the reference point.
If you did that, then the car would never move, but everything else
would.
