Two different types of neurons transmit pain signals to the central nervous system. The faster type transmits signals at 25 m/s. The slower type transmits signals at 0.5 m/s. The distance from your hand to your central nervous system is about 1 m. Suppose that you touch a hot stove. Show that you become aware of the first type of pain in 0.04 s, and that you become aware of the second type of pain after only 2 s. (You may have noticed that when you do something like touch a hot stove, you feel a flash of sharp pain first, followed by a slow throbbing pain.)
