We have the speed and time, from that we can get the rate of acceleration (pending if we launch from 0mph).
2.5s=18.78/x^2
So, the rate of acceleration would be 6.83 m/s which is a launch pulling about .25 G's.
Now, with that being said, to calculate the distance traveled we do this.
x=1/2(6.83m/s)(2.5s)2
That comes to about 21m which converts to aprox 70ft launch so yep, the launches combined would probably not be over 200ft.
Sorry this is a few days late, but I do not want anyone to be misinformed.
Acceleration is the change in velocity over time so a=delta_v/t
A=18.78 m/s / 2.5 s = 7.5 m/s^2
Gravity is 9.81 m/s^2
G-force = a/gravity ==> 7.5/9.81=.76
This is assuming constant acelleration, which is almost never the case in real life. So we are looking at a launch of about 1 or more G's. A launch of .25 G's is miserably slow.
