Answer: 540 J</h2>
Explanation:
The Work 
done by a Force 
refers to the release of potential energy from a body that is moved by the application of that force to overcome a resistance along a path.
Now, when the applied force is constant and the direction of the force and the direction of the movement are parallel, the equation to calculate it is:
(1)
In this case both (the force and the distance in the path) are parallel (this means they are in the same direction), so the work performed is the product of the force exerted to push the box 
by the distance traveled 
.
Hence:
(2)
Answer:
A quantity that does not depend on the direction is called a scalar quantity. Vector quantities have two characteristics, a magnitude, and a direction. Scalar quantities have only a magnitude. When comparing two vector quantities of the same type, you have to compare both the magnitude and the direction.
Scalar quantities only have magnitude (size). Scalar quantities include distance...
A quantity that is specified by both size and direction is a vector. Displacement includes both size and direction and is an example of a vector. However, distance is a physical quantity that does not include a direction and isn't a vector.

<u>Ques</u><u>tion</u><u>:</u>
Azaria's pet lizard runs a distance of 45 meters in 24 seconds. What is the speed of the lizard?
_________________________________________________
<u>Solu</u><u>tion</u><u>:</u>
We are given,
- Distance = d = 45 m
- Time = t = 24 s
Speed is given by:
Putting the given values,
s = (45 m)/(24 s)
=> s = 1.875 m/s
