Say you have a ball being hit from the same height with a 10 lb. versus a 20lb. weight (simulating a kick) would the distance it traveled being hit by the 20 lb. be two times the 10lb ? All other variables would be the same, I.E. controlled.
This is a followup as I apparentlly was not specific enough in the way I asked it earlier.

The formula involved would be F=ma. Since F is doubled and mass of ball, m, is the same, then a is doubled. But would doubling the acceleration make the ball travel twice the distance?
Examine the following formula to compute the distance:
s=ut+1/2at^2
Where s represents the distance travelled, u the initial velocity of the ball, and t the time the ball travelled. Since u is not 0 because of the initial force of the kick, then s will increase but it will not be doubled. s is doubled only if u is 0, which is not the case in this problem.

If everything else was the same, then you have twice the kick force. So you would think it would go twice the distance.
But ... there some forces involved that are not 2X more. Air resistance is about 8X more at double speed. Friction with the ground is a bit more than 2X at double speed.
So the ball will go less than twice as far.
