The Joy of Kayaking: Calculating Power Output and Force Exerted

How can we calculate the force exerted by a kayaker to maintain a steady speed?

If a kayaker paddles with a power output of 50.0W to maintain a steady speed of 1.50m/s, what is the force exerted by the kayaker?

Calculating the Force Exerted by a Kayaker

The force exerted by the kayaker can be calculated using the formula: F = P / v, where F is the force, P is the power output, and v is the velocity.

When a kayaker is paddling with a power output of 50.0W to maintain a steady speed of 1.50m/s, we can determine the force exerted by the kayaker by dividing the power output by the velocity.

Using the given values:

F = 50.0 W / 1.50 m/s

F ≈ 33.3 N

Therefore, the force exerted by the kayaker to maintain a steady speed of 1.50 m/s with a power output of 50.0 W is approximately 33.3 N. This force is necessary for the kayaker to overcome resistance and propel themselves through the water.

It's amazing to see the amount of force and power required for such a peaceful and enjoyable activity like kayaking! Keep on paddling and enjoying the wonders of nature.
