Answer:

9000J

Explanation:

Given parameters:

Mass of the jet fighter  = 5kg

Velocity  = 60m/s

Unknown:

Kinetic energy of the jet fighter  = ?

Solution:

The kinetic energy of a body is the energy due to motion of the body.

It is mathematically expressed as;

    K.E  = \frac{1}{2} m v²

m is the mass

v is the velocity

 So;

     K.E  =  \frac{1}{2}  x 5 x 60²  = 9000J

How many grams are in 4.65 mol of AI(NO2)3
nirvana33 [79]
To find out how many grams are in 4.65 moles of Al(NO₂)₃
Find out what the molar mass of Al(NO₂)₃ is
Al = 26.98 g/mol Al
N = 14 g/mol N
O = 16 g/mol O
Next, you have to look at the subscripts and figure out which they belong to, in this case:
Al = 26.98 g/mol Al
N₃ = 42 g/mol N₃
O₆ = 96 g/mol O₆
Finally, add the numbers together, so:
26.98 g/mol Al + 42 g/mol N₃ + 96 g/mol O₆ = 
164.98 g/mol Al(NO₂)₃
Now, you have 4.65 mol Al(NO₂)₃ so
164.98 g/mol Al(NO₂)₃ × 4.65 mol Al(NO₂)₃ =
767.157 grams of Al(NO₂)₃
