Answer:
the long wavelength and not focused on the negatives.
Answer:
Their change in momentum is the same in magnitude and opposite in direction
Explanation:
The momentum of an object is defined as:
where
m is the mass of the object
v is the velocity of the object
Therefore, the change in momentum of an object is
where is the change in velocity.
During a collision, the force experienced by an object is equal to the rate of change of momentum:
where is the duration of the collision.
According to Newton's third law of motion, the force exerted by vehicle 1 on vehicle 2 during the collision is equal (and opposite) to the force exerted by vehicle 2 on vehicle 1, so
Which means
And since the duration of the collision is the same for the two vehicles, this becomes

Answer:
25%
Explanation:
If there is 20% scrap, then
80% of (production + scrap) = 72 pcs/hr
Now,
The percent increase in labor productivity is, .
Or it can be written as 25% of which would give 80 pieces per hour.
