[khfrekek92]

Homework Statement

Consider a river of width 1000 m flowing 30 degrees east of north with a speed of 10m/s at latitude 50 degrees north. The river bottom is flat. On which side of the river is the water deeper and by how much?

Homework Equations

the only correction i need to use is -2m(omega cross v). I can't figure out what omega is.. then after that I don't know what to do. Any help?

The Attempt at a Solution

I've started it and drawn a diagram, but after that I'm lost.. any help would be great! thank you!

hi khfrekek92!

the only correction i need to use is -2m(omega cross v). I can't figure out what omega is..

ω is the angular velocity of the Earth …

it goes through the Earth's axis ​

Sorry! I meant I don't know what v is, is it the velocity of the river in vector form?
