The concept of momentum tells us that it is equivalent to the product between the mass and the velocity of the object, that is to say that in general it can be written as
Where,
m = mass
v = Velocity
Our values are given as,
Replacing we have that,
Therefore the magniude of the momentum of the pitched baseball is 
No the vector can never be shorter than one of its components
Answer:
Thickness is 217 nm
Explanation:
For a thin film, constructive and destructive interference each has its own effects. Here constructive interference causes the light to be strongly reflected. The thickness can be determined from
here n is refractive index 1.38, m=1 , 
=0, 
=600 nm
