Given :
A 2450 kg stunt airplane accelerates from 120 m/s to 162 m/s in 2.10 s.
If the airplane is putting out an average force of .
To Find :
The average friction force exerted on the airplane by the air.
Solution :
Acceleration is given by :
Now, force equation is given by :
Therefore, frictional force exerted in the airplane by the air is 9810 N.
At the same temperature . . .
<em> Fahrenheit reading = (1.8 times Celsius reading) + 32</em> .
F = (1.8 x 232) + 32
F = 417.6 + 32
<em>F = 449.6°</em>
Modern fireplaces use a CATALYTIC COMBUSTOR to burn exhaust gases.
A catalytic combustor is an attachment which allows exhaust gases to be chemically broken down to release more energy. This is how it is applicable to modern fireplaces.
Answer:
unless acted upon by an unbalanced force.
Explanation:
If a ball is rolling, it will continue to roll forever, unless it is acted upon by an unbalanced force. For example, the friction of the floor it's rolling on slows it down. The density of the air hitting it also slows it down.
