Answer:
The maximum height of the ball is 36.65 m.
Step-by-step explanation:
Given that,
Time = 5.47 sec
The ball must be at top point in half of total time.
We need to calculate the height
Using equation of motion

Where, s = height
u = initial velocity
g = acceleration due to gravity
Put the value in the equation


Hence, The maximum height of the ball is 36.65 m.
