Answer:
For an excellent understanding of the system, we must first consider that everything that all the objects within it are at rest, which implies directly that the initial moment is zero.
From this it is logical to intuit that when applying an external force on the system, the speed of the system will be generated to change.
Thus applying the law of conservation, we understand that
Initial System Moment = Final System Moment.
From this we conclude that the final moment is 0.
Momentum = 0kg-m / s

Answer:
Option C. 5,000 kg m/s
Explanation:
<u>Linear Momentum on a System of Particles
</u>
Is defined as the sum of the momenta of each particles in a determined moment. The individual momentum is the product of the mass of the particle by its speed
P=mv
The question refers to an 100 kg object traveling at 50 m/s who collides with another object of 50 kg object initially at rest. We compute the moments of each object
The sum of the momenta of both objects prior to the collision is
Answer:
b.The frictional force and force exerted by the spring scale on the block, because they are a Newton's third-law pair.
Explanation:
Students connect a spring scale to a block on a rough horizontal surface. The students use the spring scale to measure the magnitude of the horizontal force needed to pull the block at a constant speed. Which of the following statements explains why two forces exerted between objects ar equal in magnitude?
a.A The gravitational and normal forces exerted on the block, because they are a Newton's third-law pair.
b.The frictional force and force exerted by the spring scale on the block, because they are a Newton's third-law pair.
c.The normal force and the frictional force exerted on the block, because objects always exert forces of equal magnitude on each other.
d.The frictional forces that the block and the surface exert on each other, because objects always exert forces of equal magnitude on each other.
solution \
the answer will be B
for a body to travel in a horizontal direction, it must be equal in direction to the frictional force which is in opposite direction to the force applied to move the block.
Also Newton's third law of motion must be obeyed , which states that action and reaction are equal and opposite
