We have 2 model rockets identical in all ways (weight, height, mass, propellant, etc). The first rocket is launched like most rockets (0 ft/sec) and reaches 1000ft. For the second rocket we use a SUPER rubberband launch system. The launch system sends the rocket to say, 150 ft/sec before the rocket ignites. What altitude will the 2nd rocket reach? Please see the attached image.
I assume part of it involves Kinematic Equations. Something like V² = U² +2*a*s. After that do we just add together 1000+the result? Or is it far more complex? I heard that rockets perform better at speed. In theory, are the gains in altitude significant? The plan is to do a real world test! My profession is in advertising and have loved rockets since childhood, but physics is way over my head!
The Attempt at a Solution
1000 + 1147 = 2147
BAM! How's that?
