SUMMARY
The force exerted on a paddle submerged in a river can be calculated using the formula F = ρAv^2sinΘ, where ρ is the water density, A is the paddle area, v is the water velocity, and Θ is the angle between the water flow and the paddle. The discussion highlights the importance of incorporating the drag coefficient and acknowledges the potential for cavitation at high velocities, which is not covered in the referenced Wikipedia article. The user seeks clarification on their calculations and the inclusion of the factor of one-half in the force equation.
