    Resultant Velocity
Click For Summary
To calculate the resultant velocity of a boat moving at 10 m/s south and a river flowing at 3 m/s east, one can use vector addition. This involves drawing the velocities as vectors on a coordinate system, where the boat's velocity is represented as a vector pointing downward and the river's velocity as a vector pointing to the right. Applying the Pythagorean theorem will help determine the magnitude of the resultant velocity, while trigonometric functions can be used to find the angle. It's important to clarify the direction of the boat's movement, as south is typically represented by 180 degrees rather than 160 degrees. Understanding these vector principles is essential for accurate calculations of resultant velocity.

Say I have a boat moving at 10 m/s south (160 degrees) ina river that is flowing at 3 m/s east (90 degrees)

How would you calculate the resultant velocity in this instance?

Do you know about trigonometry and vectors? (hint: draw the velocities as vectors)

(by the way, are you sure you don't mean 180 degrees when you said "south"?)
