<span>The dark, smooth surface areas of the Moon are known as C. maria. Although they are a type of craters, they are not called that way, but rather their name is maria, because scientists who first researched this areas thought they were seas or oceans. In Latin, the word for sea is mare, and plural is maria, which is why these areas are also called that way because they resemble these waters.</span>
Answer:
a)
b)
c) ΔK=
d)ΔK=
Explanation:
From the exercise we know that there is a collision of a sports car and a truck.
So, the sport car is going to be our object number 1 and the truck object number 2.
Since the two vehicles remain locked together after the collision the final mass is:
a) To find the velocity of the two vehicles just after the collision we must use linear's momentum principle
b) To find the speed the truck should have had so both vehicles stopped in the collision we need to use the same principle used before
c) To find the change in kinetic energy we need to do the following steps:
ΔK=
ΔK=
d) The change in kinetic energy where the two vehicles stopped in the collision is:
ΔK=
ΔK=
