Answer:
Explanation:
The kinetic energy of an object is given by 
where 
is the mass of the object and 
is the velocity of the object.
We can set up the following equations with the information given:
For part B, we have the same equation, but kinetic energy is now 
.
Therefore:
.
Answer:
700ma
Explanation:
all u do is have to add them up.
By definition we have that the linear moment is
p = m * v
Where
m = mass
v = speed.
Clearing the mass we have
m = p / v
Substituting the values
m= (13,300 kgm/s)/(14 m/s)=950Kg
the mass of the car is 950 Kg
Answer:
B electrons protons and neutrons
hope i helped...
Explanation:
<span>The protons and neutrons are much more massive than the electrons.
</span>
The electrons are simply too small to really change the mass, so they aren't counted.
