Answer:
1.62 L
Explanation:
Charle's law for ideal gases states that for a gas kept at constant pressure, the ratio between volume and temperature is constant:
where in this problem we have
is the initial volume of the gas
is the initial temperature of the gas
is the final volume of the gas
is the final temperature
Solving the equation for V2, we find
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.
