Transcribed Image Text:Conservation of Momentum
1. A 4-kg mass slides along a frictionless,
horizontal table and collides with another 4-kg
mass initially at rest. The initial velocity of the
first mass is 2 m/sec. What is its momentum?
According to Newton's
third law, there is, for any force exerted, a(n)
...and.. ............reaction force. The
moving body will exert a force on the stationary
body, and the stationary body will exert a(n)
............and............ ....reaction force on
the moving body. We also know that the time
during which the two forces act is equal. Why?
This means that
the two bodies will receive impulses that are
...in magnitude but.....................in direc-
tion. The momentum gained by one will be
to the momentum lost by the other.
This is a form of the law of the conservation of
momentum: The total momentum of a system
on which no outside force acts remains constant.
If the first body comes to rest after it collides
with the second, what will be the final velocity
of the second body?..
