# Homework Help: Coriolis Affect question.

1. The problem statement, all variables and given/known data
Its a 3 part question but i think I already got the first 2 parts.

The first part was asking us to find the angular velocity of the spinning earth.
The second part was asking us to estimate the velocity of water moving horizontally in a sink as it drains. Using that we find the acceleration.

The third part is asking what the distance would the water be deflected to the right at this rate of acceleration across the size of the sink. Is this also enough to force the water to drain in a counterclockwise sense?

2. Relevant equations
w = delta theta/delta time to find the angular velocity
F = -2mwv to find the acceleration

But I'm stuck on what formula to use for part 3.

3. The attempt at a solution
Part 1: w = 2pie/(24x60x60) = 7.27x10^-5
Part 2: a = -2wv using w from part 1 and v I estimated at 0.04 m/s
Part 3: stuck =/

Any help is appreciated.. thanks!
