It doesnt make any sense because the diagram is wrong so I'm guessing it would be either 8 or 6. Im sorry that problem is wrong :(
Hello,
g=9.81m/s²= 9.81/0.3048 =32.18.. ft/s² rounded to 32
h=-g/2*t²+vt+h0
if t=0,h=0 ==>h0=0
==>h=-16*t²+vt
50 ft in 2.5s ==> 25 ft in 1.25s
25=-16*1.25²+v*1.25
==>v=50/1.25=40
Equation h=-16t²+40*t
<span>well 1 gallon is 4 quarts so 4 times greater</span>
They’re not equivalent because 18 divided by 6 is not the same as the quotient of 8 divided by 4
