Given:

The mass of the sugar is m = 5 kg

The distance of the shelf from the counter is h = 0.33 m

Required: Work done to put the bag on a shelf above the counter.

Step-by-step explanation:

The work done can be calculated by the formula


\begin{gathered} Work\text{ done = potential energy} \\ W=mgh \end{gathered}

Here, g = 9.8 m/s^2 is the acceleration due to gravity.

On substituting the values, the work done will be


\begin{gathered} W\text{ =5}*9.8*0.33 \\ =16.17\text{ J} \end{gathered}

Final Answer: The work done to put the bag on a shelf above the counter is 16.17 J.
