Hi, Could someone help walk me through the steps necessary to obtain the following values for u and v. I started with u = Cos(angle_between_u_and_R_wp)*R*wp and R^2 = (d+rcos(theta))^2 +(rsin(theta))^2 and just end up with a mess. Any help would be appreciated. Thanks! http://imgur.com/M5D78

The Coriolis Force EFECTO CORIOLIS Coriolis Force= Coriolis Force increases/decreases with r In the center, there is no Coriolis Force

It is not a question about forces (dynamics), but just about movement (kinematics). We just have to add the speeds as vectors. use r.sin(theta) = R.sin(angle_between_d_and_R)
