hey what does everyone know/estimate one of those three man giant elastic water ballon launchers has as its k constant in hooke's equation F = -kx(adsbygoogle = window.adsbygoogle || []).push({});

im trying to figure out a max range for one of those for a given strech length x and a given mass m.

i did 1/2 m v^2 = 1/2 k x^2 -> v = sqrt(kx^2/m) then put that all in the projectile formula basic stuff, all this seem sound? or do u think that the mass/projectile will not recive all of the spring energy? idk let me know what u guys think.
