Sandra asks…Physics formula for stopping distance?today i was learning about a car, with its reaction time and stopping distance.
If I have a car going at say 50 mph how what formula would i use to get the stopping distance (my reaction time is abut 2 seconds)Nancy answers:S = (Vo^2 - 0) / (2a) + VoTr
A useful conversion factor to memorize is 60 mph ≡ 88 fps, or 15 mph = 22 fps.
Plugging in values we know in the equation above,
s = ^2 / (2a) + (2 s)
s = (24,200 ft^2/s^2) / (3a) +
