Answer:
64.73 Watts
Step-by-step explanation:
We are given;
- Work done by the swimmer = 3,560 J
- Time, t = 55 seconds
We are required to calculate the power of the swimmer;
- We need to know that power is the rate of doing work
- That is, Power = Work done ÷ time
Therefore;
Power of the swimmer = 3,560 Joules ÷ 55 seconds
= 64.727 Watts
= 64.73 Watts
Thus, the power output of the swimmer is 64.73 watts
