Step-by-step explanation:
Given that,
The function that shows the height of a baseball after t seconds is given by :
....(1)
Part (A).
When the baseball hits the ground,
H(t) = 0
So,

After 5 seconds the baseball will hit the ground.
Pat (B)
For maximum height, put dH/dt = 0
So,

Put t = 2.34 s in equation (1).

Hence, this is the required solution.
5:9 is just 5/9
Hope this helps!
