Of course you
can find acceleration from the rate of change
of cadence plus gear ratio etc. And according to Newton,
F = ma and we know m. But that assumes that it is the force
on the pedals that causes the acceleration, which is not
always the case. And the roar of a motor is very dependent
on the work it has to do.
Chasing away from lights in the city is a pretty close
thing. This
was a fun project proposal, now it needs pulse detectors, some
accelerometers, pressure guages, a small computer, gps, 2 separate
lead acid accumultators to take care of the Omron X5MF 24V (one in
each pannier assumably), a speaker set in a rucksack and a wind vane
on a 10 meter pole.
Man, I would start suggesting that a better method would be to strap
a 2-stroke to his back and mic it up - I am sure LAU could advise on
optimal positioning.
