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.

Step-by-step explanation:
Answer:
15.12
Step-by-step explanation:
3.6 x 4.2
first aline the decmials like you would regularly do to multiply.
Then multiply 2 x 6=12 and then 2 x 3=6 and put them down were you would already do noramly multiplying.
and then muliply 4x6=24 and 4x3=12 and do the same thing as you would do normaly and then add 72 and 144 to get 1512 and then count your decmail placing. which is 2 placeing in total which makes 1512 into 15.12
and now you done!
Example of how it should look...
3 . 6
× 4 . 2
+ 7 . 2
+ 1 4 4
= 1 5 1 2
