Answer:

8secs

Step-by-step explanation:

To calculate how long the ball stays in air, we need to find the time it takes to reach the max height first

The ball reaches its max height when dh/dt = 0.

-32t+128=0

32t = 128

t = 128/32

t = 4secs

The time the ball spent in air will be;

t = 2(4)

t = 8secs

Hence the ball spent 8secs in air
