Fun Facts About Kayaking

Did you know that kayakers have to overcome resistive forces while paddling in water?

What is the resistive force exerted by the water on a kayaker paddling with a power output of 50.0 W to maintain a steady speed of 1.50 m/s?

Resistive Force on a Kayaker

The resistive force exerted by the water on the kayak is 33.3 N.

When kayaking, paddlers need to exert force to maintain their speed in the water. The resistive force acting against them is determined by their power output and velocity.

The formula to calculate the resistive force is:

Resistive force = Power output / Velocity

In this scenario, the kayaker has a power output of 50.0 W and is moving at a speed of 1.50 m/s. By substituting these values into the formula, we can find the resistive force:

Resistive force = 50.0 W / 1.50 m/s = 33.3 N

Therefore, the resistive force exerted by the water on the kayak is 33.3 N. It's amazing how kayakers can overcome this force to enjoy their paddling adventures!
