Answer:
P V = N R T ideal gas equation
V1 = k * T1 if P is constant and also N and R will be constant
V2 = k * T2 where k is some constant
Or V2 = (T2 / T1) * V1 also known as "Charles Law" for expansion at
constant pressure
V2 = (373 / 273) * 1000 cm^3 = 1366 cm^3 where T is absolute temperature
<span>a = (v2 - v1)/t = (10 - 6)/2 = 2 m/sec/sec (average acceleration)</span>
In order to calculate his velocity for the whole session, we need to know ...
(1). the straight-line distance from the start-point to the end-point;
(2). the direction from start-point to end-point
(3). the elapsed time from start to finish
We could find (1) and (2) if we knew how much time he spent on each segment of the training run. Then we could calculate the distance covered on each segment, and construct the straight-line displacement and direction of the whole thing.
For (3), no time information is given anywhere in the question, so it's pretty hard to come up with a total time.
We definitely have to mark this one "<em>INSUFFICIENT GIVEN INFORMATION</em>". We just don't have what we need in order to solve it.
