question 23 of 25\na mailman performed 588 j of work lifting a box 1.4 m. how much force did the mailman…

Explanation:

Step1: Recall work - force - distance formula

The formula for work is $W = F\times d$, where $W$ is work, $F$ is force, and $d$ is distance. We need to solve for $F$.

Step2: Rearrange the formula for $F$

Rearranging $W = F\times d$ gives $F=\frac{W}{d}$.

Step3: Substitute given values

We know that $W = 588\ J$ and $d = 1.4\ m$. Substituting these values into the formula $F=\frac{W}{d}$, we get $F=\frac{588}{1.4}$.

Step4: Calculate the force

$\frac{588}{1.4}=420\ N$.

Answer:

A. 420 N
