| I asked for an
explanation for the following . . . |
| 1. |
to find an explanation for
the maximum at the top left (B); and, |
| 2. |
the maximum at the lower
left (C). |
Line D is the line
that corresponds to the maximum flight time for a
given mass of rocket which matches well the maximum
height - flight time being related to the amount of
time it takes a rocket to fall from the sky.
Area A is the useful
maximum for this as it is normally not possible to
get a rocket that weighs 1.1 grammes with a capacity
of 2 litres.
The far left of the plot has the
property that the size of the rocket and its weight
is such that the rocket will float down to earth
rather than plummet in the usual manner. In this way,
if the rocket can be given some altilude by pushing
it there, it will take a while to float back to
earth. Area B represents a flight
where the rocket is pushed up almmost to its maximum
altitude by the water at which point it virtually
stops and then floats back to earth.
Area C is where this
left hand side phenomenon coincides with the maximum
height to give another peak.
