Given information
As per the given question ,
Initial velocity of the second child is 
Acceleration due to gravity always acts downwards,
Step-by-step explanation
Step 1.
To determine the maximum height of the second child we will use Third equation of Motion ,
The third equation of motion:
Where, 
is the final velocity, 
is the initial velocity, 
is the acceleration and 
is the displacement
At the maximum height, velocity would be zero. 
Substitute the values and solve.
