Answer:
Expression of work done is
Work done to move the sled is given as 1.94 J
Explanation:
As we know that the formula of work done is given as
here we know that
F = 6 N
d = 0.4 m
so we will have
The total quantity of an object's matter is called its

Answer:
2324 J
Explanation:
The formula for work is:
where is the force applied, and
is the distance moved, in this case
and we need to find
Since the crate is not moving up or down, we conclude that the <u>normal force must be equal to the weight </u>of the object:
where is the normal force and
is the weight, which is:
, where g is the gravitational acceleration
and
is the mass
.
---------
Thus the normal force is:
Now, the force due to the friction is defined as:
where is the coefficient of friction,
So, for the crate to move, the force applied must be equal to the frictional force:
And now that we know the force we can calculate the work:
substituting known values:
