Answer:
The answer is 2.28 seconds
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
