Answer:
Workdone = 19600 Nm
Explanation:
Given the following data;
Mass = 40 kg
Distance = 50 meters
We know that acceleration due to gravity is equal to 9.8 m/s².
To find the work done;
First of all, we would determine the force being exerted by the construction worker.
Force = mass * acceleration due to gravity
Force = 40 * 9.8
Force = 392 Newton
Next, we would determine the work done;
Workdone is given by the formula;
[tex] Workdone = force * distance[/tex]
[tex] Workdone = 392 * 50 [/tex]
Workdone = 19600 Nm
