Q: Pilot in a Plane - Which Ball Hits Ground First?

[Minibyte]

If one ball is dropped and another is thrown down, which will arrive at the ground first?

Won't they get there at the same time?

Thanks

Your question is vague. Are the balls dropped and thrown at the same time? Assuming they are the down thrown will arrive first. You need to solve for t in the equation:
h-vt-.5gt²=0, where h is the initial height, v is the initial speed, and g is the gravitational constant. Air resistance is neglected - however, if both balls are the same the net effect will be the same on both.

For the dropped ball v=0 while the thrown ball starts with v>0, so t will be less.

Yes, dropped and thrown at the same time. No other information provided. No velocity, speed, just that vague question.
