Answer:
26.45 m
Step-by-step explanation:
Initial velocity = 23m/s
At maximum height final velocity of the voleyball will be 0 . So ,
Final velocity= 0m/s
Acceleration due to gravity = -10m/s² (taking upward direction as +ve ) .
On using third equation of motion ,
=> 2as = v² - u²
=> 2*10*s = 0² -(23)²
=> s = 23*23/20
=> s = 26.45 m
Hence the maximum height attained by the ball is 26.45m
