Question

A swimmer does 3,560 J of work in 55 s. What is the swimmer's power output? Round your answer to two significant

Answer 1

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
