Answer:
The ball reaches Barney head in
Explanation:
From the question we are told that
The rise velocity is
The height considered is
The horizontal velocity of the large object is
Generally from kinematic equation
Here s is the distance of the object from Barney head ,
u is the velocity of the object along the vertical axis which is equal but opposite to the velocity of the helicopter
So
So
=
Solving the above equation using quadratic formula
The value of t obtained is
