Answer:
An independent variable is a variable that is manipulated to determine the value of a dependent variable. The dependent variable is what is being measured in an experiment or evaluated in a mathematical equation and the independent variables are the inputs to that measurement.
Explanation:
Answer:
Time will be 5 sec
And maximum height will be 1200 feet
Explanation:
We have given that initial velocity of the object u = 160 ft/sec'
Function of height 
Take derivative of the distance
We know that first derivative of distance is velocity
So 
At maximum height we know that velocity is zero
So 
t = 5 sec
So it will take 5 sec to reach maximum height
Now maximum height will occur at t = 5 sec
So maximum height = 
3.5 meters per second
60sec=1min
60min=1 hr
3.5*60*60= meters per hour
=12600
1000meter= 1 km
12600/1000= km per hr
=12.6 km per hour
