Reaction Time Java Applet
Would you like to measure your reation time? Would you like to estimate how fast you can drive on the highway?
Try this. Just Press
Your browser can't run 1.0 Java applets, so here's a picture of the window the program brings up:
What you need to do: Click the Brake button when the red light turns on. (Not just pressed on it)
Reaction time : the lapse of time between stimulation and the beginning of response.
You are driving on the high way and listening to the music you like most.
Suddently, you see the brake light of the car in front of you just turned on.
You will try to hit the brake and slow down your car.
But, there is a small time delay before you really do that--- your reaction time.
During that period of time, your car is still moving at the same HIGH speed!
If you do not want something VERY BAD happened,
What is minimum diatance between front of your car and the rear of the car before yours?
If both cars need the same distance to fully stopped, the miniuum distance is
( the velocity of your car )* ( your reaction time )
