## Homework Statement

Find the magnitude and direction of the Coriolis force on a racing car of mass 10 metric tons traveling due south at a speed of 400km/hr at a lattitude of 45 degrees north.

## Homework Equations

[tex]F_{cor}=-2m\omega\times v[/tex]

## The Attempt at a Solution

[tex]\omega=2\pi/(24*3600 \quad seconds)[/tex]

[tex]v=400km/hr=400/3600 \quad km/second[/tex]

[tex]m=10000[/tex]

[tex]-2 m\omega\times v=-2m\omega v sin(45) \quad Newtons \quad east = -114.27 \quad Newtons \quad east = 114.27 \quad Newtons \quad west[/tex]

The answer in the back of my book says "41 nt west"
