Answer:
Step-by-step explanation:
So, as balloon reaches its maximum height i.e. 11 m , its velocity become 0.
Therefore, .
It is given that acceleration due to gravity should be taken as , .(because it direction is down)
Now it is also given that upward direction is positive and downward direction is negative. So velocity should be negative.
Using equation of motion,
.....eqn 1.
where , displacement = -11 m(because it displace towards down) and
Putting these values in eqn 1 .
But as we know direction of velocity is downward.
Therefore,
where negative sign indicates its direction is downward.
