Amailman performed 180 j of work lifting a box 0.8 m. how much force did the mailman use?

The mailman used a force of 225N.

Step-by-step explanation:

The work formula is given by:

In which W is the work, F is the force and l is the length of the object.

In this problem, we have that:

A mailman performed 180 J of work lifting a box 0.8 m. This means that . So

The mailman used a force of 225N.

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

all it means is function 3
