comment Finding instantaneous speed in MPH given acceleration, RPM and gear ratio
There you go @Alexander - I couldn't find any specific issue with the previous website, but happy to change.

comment Do you pay more for gas when the day is warmer?
But your engine is much more efficient with cold air - as it is more dense. Wonder where the two curves would balance out :-)

comment Why do rockets accelerate fastest horizontally?
But surely you need to take the most obvious case - which is from zero to x seconds. If you take too long, the rocket will have hit the ground (as per your answer) and as that will happen relatively rapidly, terminal velocity is not really going to become a major factor here.

But you will also hit terminal velocity in the other directions as well. It will just take longer as acceleration is lower.

QI does get things wrong - sometimes they admit their mistakes on later shows, other times they don't. :-)

comment Why are there more vertical takeoff than horizontal for spacecrafts?
Yes, but they couldn't do it successfully, which is why it is only recently beginning to work.
