Answer:
The mass is 36.33 kilograms.
Explanation:
The work is defined as the force needed to move an object a certain distance, if there's no change of position, there's no work.
In this case, the work is defined:
\(W=Fd\)
Where \(F\) is the weight defined with the following equation
\(F=W=mg\)
Now, we'll replace all given values and solve for \(m\):
\(W=mgy\\178=m(9.8)(0.5)\\m=\frac{178}{4.9}=36.33 kg\)
Therefore, the mass is 36.33 kilograms.
