It takes 7.0s for a piece of wood to be falling from a tall building in the velocity of 68.6 m/s
<u>Explanation:</u>
v = u + at
68.6 ms^-1 = 0 ms^-1 + (9.8 ms^-2 x t)
t = 68.6 ms^-1 / 9.8 ms^-2
t = 7.0s
It takes 7.0s for a piece of wood to be falling from a tall building in the velocity of 68.6 m/s

Given that,
The equation below show the total amount of water in gallons, y that has flowed through two different types of showers heads after x minute.
Type A: y =1.25 x
Type B: y= 2.50 x
So,
The amount of water per minute is 
For type A
y =1.25 x
For type B
y =2.50 x
The amount of water flowed through Type B is twice that flowed trough type A per minute.
