How long would it take an impulse to travel from the top of a 5-foot person's body to the bottom of their feet?
qwelly [4]

Answer:

Total time taken = 0.01524 seconds

Explanation:

Given:

Distance travel by impulse = 5 feet

Assume;

Speed of impulse = 100 m/s

Find:

Total time taken

Computation:

1 feet = 0.3048 meter

Distance travel by impulse = 5 feet = 5[0.3048] = 1.524 meter

Total time taken = Distance travel by impulse / Speed of impulse

Total time taken = 1.524 / 100

Total time taken = 0.01524 seconds
