Velocity
Note : Not speed as Acceleration is a vector!
-17.555m/s
first I found the time it took for jacks stone to reach the bottom, using the formula vf = vi + at, vf and vi are final and initial velocities.
then i found the velocity at 6.6m using vf^2 = vi^2 + 2ad
and I found the time it took to get to 6.6m, so that I knew how long Jill waited to throw her stone, I used the formula d = t(vi+vf)/2, then i done total time - the time she waited, to get the time it took for there stones to hit the ground at the same time.
then to find the initial velocity of her throw I used the formula d = vit + (at^2)/2
Answer:
Required diameter of hose pipe = 0.2864 mm
Solution:
From the continuity eqn, the fluid flow rate is given by:
Av = 
where
A = cross-sectional area = 
r = hose pipe radius
v = velocity of gas
Also, 
Using:
1 gallon = 3.854 l
1 mile = 1609.34 m
Therefore,
The diameter of the hose pipe = 2r = 
The diameter of the hose pipe =
