answer:

see below

step-by-step explanation:

part a: from the graph you can see that the graph is increasing between 0 and 2.  

part b: the height is staying the same where the graph is a horizontal line. (slope of zero) between 2 and 4.  

part c: the balloons height is decreasing the fastest from 8 to 10.   this is where the graph has the steepest negative slope.  

part d:   from the graph- at 14 seconds the balloon remains on the ground as it hit the ground at 10 seconds.   height would = 0
