A lamb grows with its mass proportional to the cube of its length. When the lambs length changes by 15.8% its mass increases by 17.3kg. Find the final mass.
Really stumped thanks for any help
mf=kxf3
length change by 15.8%
xi+.158xi=xf
xf=1.158xi
mf=k(1.158x)3
mf=1.55kx3
I couldn't get the right answer because at this point, my book shows kx3 turning into mi and continuing the problem from there. Why?
kx3=mi
mf=1.55mi
mi=mf/1.55
