Volume of a Cylinder = pi * r^2 * h
V / (pi*r^2) = h
12157 / (pi * 9^2) = h = 47.774
Answer and work down below
6; because they are an equal distance apart
Acceleration is simplified by assuming it is the constant -g
a=-g we integrate this with respect to time to get v...
v=-gt+C where C is the initial velocity in this case 14ft/s so
v=-gt+14 integrate again to get the height function
h=(-gt^2)/2 +14t +C we are not given an initial height so C is 0
h(t)=14t-gt^2/2 letting g=32 and neatening up a bit...
h(t)=14t-16t^2
