Question

A mailman performed 180 J of work lifting a box 0.8 m. How much force did the mailman use?

Answer 1

The amount of force would equal 225 N 
since W = F x d

Answer 2

Answer:

The mailman used a force of 225N.

Step-by-step explanation:

The work formula is given by:

$W = F*l$

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 $W = 180, d = 0.8$. So

$W = F*l$

$180= F*0.8$

$F = \frac{180}{0.8}$

$F = 225$

The mailman used a force of 225N.
