Answer :
Answer: To get the wheelbarrow across the yard in 11 s Is required 9,100 J of work.
Explanation:
Hi, to solve this problem we have to apply the formula:
Power (w) = work (J) / time (sec)
So, replacing the variables with the values given:
830 w = work / 11sec
Isolating work we have:
830 w / 11 sec = work
Work = 9,130 J = 9,100 j (rounded to two significant figures)
To get the wheelbarrow across the yard in 11 s Is required 9,100 J of work.
Feel free to ask for more if it´s necessary or if you did not understand something.
