Work would be $833 J$ $833J$

To find work we need to know that

$work = F d$ $"work"=Fd$

Where $F$ $F$ is force and $d$ $d$ is distance

In this case $F = m g$ $F = mg$ because our acceleration vector would be equal and opposite to $g$ $g$ the force of gravity. So now we have:

$work = m g d = [5.0 k g] [9.8 \frac{m}{s^{2}}] [17 m]$ $"work"=mgd=[5.0kg][9.8m/s^2][17m]$

$work = 833 J$ $"work"= 833J$
