If i throw a stone(say 1kg) with the angle of(say 60 degree),then the stone goes in projectile motion and finally reach the ground(say 10m from the beginning),then how much POWER did i use in that throwing? What formulea should i use to calculate it?
Anyone~~~???
Thanks,....!!

unable to figure this out . . .
did the stone continue to travel after it hit the ground?
Was the ground concrete of grass or sand?
What was the wind direction and velocity?
Was the stone aerodynamic (smooth, rough)? (wind resistance)
How dense was the stone? (wind resistance)
The answer to this question will not be exact without all the contributing factors.
