Question

The speed of a nerve impulse in the human body is about 100 m/s. If you accidentally stub you toe in the dark, estimate the time it takes the nerve impulse to travel to your brain. (Assume that you are approximately 1.80 m tall and that the nerve impulse travels at uniform speed.)_____ s

Answer 1

We wil determine the time it takes to travel as follows:

`t=(1.80m\ast1s)/(100m)\Rightarrow t=0.018s`

So, it would take 0.018 s.
