- Homework Statement
- A boat is traveling upstream in the positive direction of an x

axis at 14 km/h with respect to the water of a river. The water is

flowing at 9.0 km/h with respect to the ground.What are the (a)

magnitude and (b) direction of the boat’s velocity with respect to

the ground?

- Relevant Equations
- For direction : θ=tan^(-1)〖Y/X〗

For Magnitude: √(A^2+B^2 )

**Homework Statement:**A boat is traveling upstream in the positive direction of an x

axis at 14 km/h with respect to the water of a river. The water is

flowing at 9.0 km/h with respect to the ground.What are the (a)

magnitude and (b) direction of the boat’s velocity with respect to

the ground?

**Homework Equations:**For direction : θ=tan^(-1)〖Y/X〗

For Magnitude: √(A^2+B^2 )

The formula for magnitude is √(A*A)+(B*B) but simply subtracting the magnitude of speeds and the farmula of direction is θ=tan INVERSE(Y/X).

but simply shows the direction into +ve and -ve x-axis. what is the best solution of the problem?
