dV/dt=kv what is a typical constant for k, i know it varies so lets just say a baseball at sea level(im sure you all can guess why im asking this.... ) Also is there a way to calculate this "k"...

any help greatly appreciated thanks!

It depends very much on the shape and texture of objects, if you use the formula [tex]D = \frac{1}{2}CA\rho v^2[/tex]. For a spherical body like the baseball it should be around 0.5.

Have a look here also: http://www.ac.wwu.edu/~vawter/PhysicsNet/Topics/Dynamics/Forces/DragCoeficientValues.html [Broken] for a table of constants.
