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.

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
