Answer:

The answer is 2.28 seconds

Step-by-step explanation:

Given data:

Work done = 8000J

Distance , d = 30 m

Power , P =3500 W

We know that

(a) Work done = force × distance

8000 J = F x 30 m

F = 8000 J / 30 m

= 266 N

(b) Power = work done / time taken

3500 W = 8000 J/ time taken

3500 W x time taken = 8000 J

Time taken = 8000 J / 3500 W =2.28 s
