Answer:
Maximum height attained by the ball will be h = 28.416 m
Step-by-step explanation:
We have given initial speed of the ball u = 23.6 m /sec
At maximum height velocity will be zero so final velocity v = 0 m/sec
Acceleration due to gravity

From law of motion we know that


h = 28.416 m
So maximum height attained by the ball will be h = 28.416 m
