Thank you. Is there is no other way to calculate the z co-ordinate without this data? But to see how it would be solved with the required data, let's assume the air resistance coefficient is 0.3.

Sorry for the lack of clarity. I misused the terminology; I meant side spin speed. 4.1m/s is the speed of the side spin. Another calculation of the same concept that I have is just rate of spin, which is 17.8 rps again in the z direction. By the way, it is anti clockwise rather than clockwise...

But how can Fz equal zero if there is clearly a spin and angular velocity in its direction. Furthermore, this is a question to obtain a theoretical model based off of experimental data which clearly shows an angle phi (between the landing position and the launching device) in the z direction...

Homework Statement A perfectly spherical ball is launched horizontally with a linear velocity of 9.9 m/s and an angular velocity (perpendicular to its trajectory) of 4.1 m/s. The ball's mass is 5.0g. (Diagram for explanation of coordinate system)...

I'm not really sure. Thanks for your help, this was just another attempt at finding a method to calculate theoretical values for the rate of spin and velocity of a ball launched out of a pitching machine consisting of two variably rotating wheels.

For my investigation regarding the aerodynamic forces on a spherical projectile, I really need to know the theoretical ratio of rotational kinetic energy to linear kinetic energy of a spherical projectile (assuming the only spin is forward spin and there is no Magnus effect). Can someone please...
