I took it, I find it interesting but pretty difficult, It all depends on who you are asking though. :)

<span>An experiment designed so that you can observe the differences between the experimental group and the control group.
In each experiment there have to be two groups - an experimental one (which has a different variable), and a control group. Both of these groups are subjected to the same thing except for that variable you are trying to test via an experiment.

Answer:
0.447 sec
Explanation:
velocity = distance/ time
distance 'h' is a function of time 't' given by
⇒ differentiating equation
⇒ velocity = 
⇒ acceleration = 
= 24 
deceleration due to gravity = -9.8 m/
= - 9.8 x 3.281 = - 32.154 ft/
Net deceleration = 24 - 32.154 = - 8.15 ft/
at maximum height v = 0
= 
+ 2ah
⇒ 0 = 
+ 2 (-8.15)h
⇒ h = 118.72 ft⇒
118.72 = 12
+ 44t + 16
⇒ 
- 102.72 = 0
⇒ t = -44 ± 
/ (2 x 12)
t = 0.447 sec
