A balloonist happens to drop his metal ballpoint pen from his balloon as he is taking notes on his flight. Because his pen has a

streamlined shape, air resistance has little effect on its fall. The pen strikes the ground at 22 m/s. How high was the balloon?

So this is dealing with the conservation of energy. So you set kinetic energy equal to potential energy, so it looks like this:

1/2mv^2=mgh. The m's cancel out, so it is 1/2v^2=gh.

To find out what the height h is, divide g on both sides, so...

h=0.5v^2/g. v=22m/s, g=9.81m/s^2, so h=(0.5)(22^2)/(9.81)=24.67m

What are the similarities and differences between how living and non-living things fly.
Nimfa-mama [501]

Flying animals utilize their wings to create both lift and propulsion by moving them in relation to the body.

<h3>What are living and nonliving things?</h3>

They both consist of fundamentally simple building blocks. They are composed of substance or mass. Atmospheric and molecular building blocks make up the world.

The differences between how living and non-living things fly;

1. Moving both living and non-living objects consumes energy. Flying animals utilize their wings to create both lift and propulsion by moving them in relation to the body.

In contrast to most air vehicles where the components that generate lift wings and thrust engines or propellers are distinct and the wings stay stationary.

Animal aviators like birds as well as natural parachuters like patagial as well as human inventions like aircraft as well as rockets that can power spacecraft and spaceplanes are just a few examples of the many things that can fly.

Hence there are similarities and differences between how living and non-living things fly.

It took 2.5 hours for the bus to travel the distance between two cities at a velocity of 75.0 miles/hr. How many miles lie betwe
makvit [3.9K]
Velocity of the bus = 75 miles/hr
Time taken by the bus to travel the distance between two cities = 2.5 hours
Let us assume the distance between the two cities = x
Then
Velocity = Distance/Time taken
Then Distance = Velocity * Time taken
                         = 75 * 2.5 miles
                         = 187.5 miles.
The distance between the two cities is 187.5 miles.I hope this answer is what you were looking for. This process is applicable for similar problems. In future you can always use this method to determine the answer.
