First, we need to determine the weight of the bricks.
The weight of a brick can vary depending on the type and size, but for this calculation, we will assume an average weight of 4 kg per brick.
Next, we need to calculate the total weight of the bricks being lifted.
Since we know that there are 225 bricks, we can multiply the weight per brick (4 kg) by the number of bricks to find the total weight:
Total weight = 4 kg/brick * 225 bricks = 900 kg.
Now, we can calculate the work done using the formula:
Work = force * distance.
The force required to lift the bricks is equal to the weight of the bricks.
The distance is given as 1.75 m.
Plugging in the values:
Work = 900 kg * 9.8 m/s^2 * 1.75 m = 15,735 J.
Therefore, the amount of work done by the worker is 15,735 Joules.
