Question
A swimmer moves through the water at an average speed of $0.22 \mathrm{~m} / \mathrm{s}$. The average drag force is $110 \mathrm{~N}$. What average power is required of the swimmer?
Step 1
Work is given by the formula: Work = Force × Distance In this case, the force is the drag force (110 N) and the distance is the distance the swimmer moves through the water. Since we know the swimmer's speed (0.22 m/s), we can find the distance by multiplying Show more…

Swimmer A swimmer moves through the water at a constant speed of $0.22 \mathrm{~m} / \mathrm{s}$. The average drag force opposing this motion is $110 \mathrm{~N}$. What average power is required of the swimmer?
A swimmer moves through the water at a speed of $0.22 \mathrm{~m} / \mathrm{s}$. The drag force opposing this motion is $110 \mathrm{~N}$. How much power is developed by the swimmer?
What average power would a 1.0x103 kg speedboat need to go from rest to 20.0 m/s in 5 s, assuming the water exerts a constant drag force of magnitude 500 N and the acceleration is constant?
