Hi guys, there is a problem I am having hard time interpreting, so I wonder if you can share your thoughs. Here it is. 1. The problem statement, all variables and given/known data a projectile is launched due north from a point in colatitude /theta at angle pi/4 to the horizontal and aimed at target whose distance is y (small compared to earth radius). Show that if no allowence is made for the effects of coriolis forc, the projectile will miss it's target by a distance x=w* ((2*y^(1/3))/g)^(1/2)*(cos(theta)-1/3sin(theta) 3. The attempt at a solution well here is my attempt you calculate components of acceleration due to coriolis force. What confuses me, what exactly is meant by distance y. Do you treat it as vertical distance above the earth, or distance to target from launching point. Also, how to determine the launching velocity, since it is needed for coliosis force. My initial guess is to say that velocity is zero at height y, but which height to use? I am thinking that once components of accelerations are calculated that question is simply finding distance between two points in the plane. So any suggestions, comments?
