Answer:
Car B has a mass of 800 kg.
General Formulas and Concepts:
<u>Momentum</u>
Law of Conservation of Momentum:
Explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
[Given] m₁ = 1200 kg
[Given] v₁i = 10 m/s
[Solve] m₂
[Given] v₂i = 0 m/s
[Given] vf = 6 m/s
<u>Step 2: Solve for m₂</u>
- Substitute in variables [Law of Conservation of Momentum]: (1200 kg)(10 m/s) + m₂(0 m/s) = (1200 kg + m₂)(6 m/s)
- Multiply: 12000 kg · m/s = (1200 kg + m₂)(6 m/s)
- Isolate m₂ term: 2000 kg = 1200 kg + m₂
- Isolate m₂: 800 kg = m₂
The molecules of the water do not change, because you have not added any other chemicals. that’s why water does not change it just only that liquid water is more dense than solid water (ice) ice is less dense.
Yes, many professional athletes will take dance classes to improve their skills. Such as football players to improve their footwork and use other muscles they wouldn't use while doing just push ups.

Answer:
Inertia
Explanation:
The term for the tendency is inertia.
<em>The inertia of a body is the tendency of the body to remain unmoved when at rest and the tendency to keep moving when in motion. In other words, it is the tendency of a body to remain in a state of rest or motion. </em>
A static body will remain in a state of perpetual rest if no force acts on it and a moving body will keep moving in the same direction if no force acts on it. The force that needs to be overcome in order to change the state of the object is otherwise known as inertia force.
