Answer:
Explanation:
There are a couple of assumptions I had to make here and also a couple of rules based on what I use in my classroom when I teach the Law of Momentum Conservation. First of all, I am going to call the 8kg ball 1 and say that it is moving to the right (and right is positive), and that means that the 3kg ball is ball 2 and say that it is moving to the left (and left is negative). I had to assume that the 2 balls were moving towards each other; hence, the different signs assigned to their movement. I also added in another significant digit since we have only 1 in most of these values and adding in a .0 is not going to change the value of any number. The Law of Momentum Conservation in this particular instance says
which is the mathematical way of saying that the momentum after the collision is the same as the momentum before it. Filling in:
and doing the math here simplifies to
32 - 42 = -16 + 3.0v and
-10 = -16 + 3.0v and
6.0 = 3.0v so
v = 2.0 (and the positive indicates that ball 2 is now moving to the right)
Answer: Because of Inertia
Explanation: According to Newton first law, that a body in a linear motion will continue to be in motion except an external for act on it
But also, a body in motion will always like to continue in motion and have a reluctance tendency to stop because of inertia.
the crash test dummies' bodies will continue to move forward even though the car stopped because of inertia.
Carbon compounds move through plants and animals, the ocean, the air, and throughout our planet. Carbon present in our atmosphere as carbon dioxide contributes to the"Greenhouse Effect" and related global warming. Carbon cycle used to described the flow of carbon in various form such as carbon dioxide CO2, organic matter, and carbonates through the atmosphere, body of water, terrestrial biosphere, and lithosphere.
I reckon it would be centimetres (cm).
