Answer: 5000 joules.
Explanation: Work is defined by the movement caused by a force, so the work can be described by the equation W = F*d
where W is work, F is force and d is distance.
In this case, the force is 500N and the distance is 10M (the time-lapse does not mater in this case)
Then we have: W = F*d = 500N*10m = 5000N*m = 5000j
The total work done is 5000 joules.
