Answer
Work = 2300 joules
Work Step by Step
Since there was no acceleration, the force the workers used was equal in magnitude to the frictional force.
Therefore, the formula
Work = Force x Distance
becomes
$Work = F_f\times d$
next, we use this formula to find the amount of work:
$Work = F_f\times d$
$Work = F_N\times\mu\times d$
$Work = mg\times\mu\times d$
$Work = (46.0)(9.8)(0.50)(10.3)$
$Work = 2300 ~joules$
