Atourist is walking at a speed of 1.3 m/s along a 9.0-km path that follows an old canal. if the speed of light in a vacuum were 3.0 m/s, how long would the path be, according to the tourist?

The length of path according to the tourist is 8111.10 meters.

Explanation:

It is given that,

Speed of tourist, v = 1.3 m/s

Path length, L₀ = 9 km = 9000 m

If the speed of light in a vacuum were 3.0 m/s. We need to find the length of path according to the tourist. Let it is L. It is a case of length contraction.

So,

L = 8111.10 m

So, the length of path according to the tourist is 8111.10 meters. Hence, this is the required solution.
