Well..

I had experiment about springs...

I got this R = K x^2 / m g.. formula to explain...

where

R = range (displacement of x)

K = constant of spring (elastic)

x = extension of spring

m = mass

g = gravity

Can anybody prove this formula for me??

It says use conservation of energy and 4 formulae of projectile motion..

I'd really appreciate if anybody can prove it...

PS it is fired at angle of 45 degrees
