Answer:

v=-1.46 \ m/s

Step-by-step explanation:

So, as balloon reaches its maximum height i.e. 11 m , its velocity become 0.

Therefore, v_{top}=0 \ m/s.

It is given that acceleration due to gravity should be taken as , g=-9.8 \ m/s^2.(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,

v_{final}^2 - v_{initial}^2 =2\times a\times displacement   .....eqn 1.

where , displacement = -11 m(because it displace towards down) and a=g=-9.8\ m/s^2

Putting these values in eqn 1 .

v_{final}^2-0^2 =2\times 9.8 \times 11

v = \pm1.46 m/s.

But as we know direction of velocity is downward.

Therefore, v=-1.46 \ m/s

where negative sign indicates its direction is downward.

strojnjashka [21]
Y=8x+12

y=8(32)+12
y=256+12
y=268

y=8(24)+12
y=192+12
y=204

204+268=$472

The instructor makes $472 a month.
