Explanation:

2 sig figs

Answer 2

64.73 Watts

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
