Answer:
13.09 s
Step-by-step explanation:
From the question given above, the following data were obtained:
Power (P) = 275 W
Work (W) = 3600 J
Time (t) =?
Power is defined as the rate at which work is done. Mathematically, it can be expressed:
Power (P) = Work (W) / time (t)
P = W/t
With the above formula, we can obtain the time taken for the swimmer to accomplish the work. This can be obtained as follow:
Power (P) = 275 W
Work (W) = 3600 J
Time (t) =?
P = W/t
275 = 3600/t
Cross multiply
275 × t = 3600
Divide both side by 275
t = 3600 / 275
t = 13.09 s
Thus, it will take the swimmer 13.09 s to accomplish the work.
