<span>Answer:
Force is a vector. If you have one force pointed northeast and another northwest the east/west component would cancel each other out. The arithmatic sum of their magnitudes is the whole force.
If you have equal forces, one going north and one south, the net force would be 0 no matter how large the arithmetic sum might be.</span>
The key thing we look for is <u>WATER.</u> We need to analyze whether a world is a possible home to life if it has the past, present, and future existence of liquid water.
Even if the planet has evidence of atmospheric oxygen, it is still insufficient for humans to live in it if it lacks H2O.
Some may argue that the presence of organic molecules such as amino acids should also be taken into account. Even if they have a valid point, it is not the most significant factor that we consider when deciding if the world is a possible home for life.
Aside from water, the world's surface color changes that indicate vegetative growth can be critical in ensuring that the world is habitable. However, vegetative growth is insufficient to be significant if the planet lacks a consistent source of water.
The first confirmed Earth-size planet where liquid water might accumulate on the surface is Kepler-186f. The discovery of another world provides evidence that there are planets in other stars' habitable zones.

Answer:
Explanation:
Impulse on an object is given by .
However, it's also given as change in momentum (impulse-momentum theorem).
Therefore, we can set the change in momentum equal to the former formula for impulse:
.
Momentum is given by . Because the truck's mass is maintained, only it's velocity is changing. Since the truck is being slowed from 26.0 m/s to 18.0 m/s, it's change in velocity is 8.0 m/s. Therefore, it's change in momentum is:
.
Now we plug in our values and solve:
(two significant figures).
