Answer:
Explanation:
Acceleration is equal to the change in velocity over the change in time, or
where the change in velocity is final velocity minus initial velocity. Filling in:
Note that I made the backward velocity negative so the forward velocity in our answer will be positive.
Simplifying that gives us:
and then isolating the final velocity, our unknown:
3.0(6.0) = v + 3.0 and
3.0(6.0) - 3.0 = v and
18 - 3.0 = v so
15 m/s = v and because this answer is positive, that means that the car is no longer rolling backwards (which was negative) but is now moving forward.

Explanation:
Explanation:
In a chemical formula, the symbols for each element in the compound are followed by subscripts that tell us how many of that element are in the compound.
For an example, let's look at the the formula for compound glucose:
C
6 H
12 O
6
________
The subscripts that follow each element's symbol indicate how many of that element are in the compound.
Answer:
This means C.the car uses 20% of the energy store in the gasoline for motion.
