Answer: The work done on the flagstone is 20178 J

Step-by-step explanation:

Power is the rate at which work is done . It is equal to the amount of work done divided by the time it takes to do the work.

Work=Power* time

Given : work = ?

Power = 342 W = 342J/s

Time = 59 s

Work=342J/s* 59s=20178J

Thus the work done on the flagstone is 20178 J
