The answer is below
Step-by-step explanation:
A) From 0 to 2 seconds, the height of the water balloon is increasing from 26 feet to 34 feet (8 ft increase) i.e. at a rate of 4 ft/s (8ft/2 s)
B) From 2 to 4 seconds, the height of the water balloon is held constant at 34 feet, also from 10 to 12 seconds the height is constant at 0 feet
C) From 4 to 8 seconds, the height of the water balloon is decreasing from 34 feet to 30 feet (4 ft decrease within 4 seconds) i.e. at a rate of 1 ft/s (4 ft /4 s).
Also From 8 to 10 seconds, the height of the water balloon is decreasing from 30 feet to 0 feet (30 ft decrease within 2 seconds) i.e. at a rate of 15 ft/s (30 ft / 2 s).
It is decreasing fastest from 8 to 10 seconds
D) At 10 seconds, the height of the balloon is at 0 feet, this means it is on the ground. It would continue to remain on the ground even at 14 seconds
