(a) How fast would an athlete need to be running for a 100-m race to look 100 yd long? (b) Is the answer consistent with the fact that relativistic effects are difficult to observe in ordinary circumstances? Explain.

To determine

(a)

The speed would an athlete need to be running for a 100-m race to look 100 yd long.

Explanation

Given info:

c=3×108 ms1

L0100 m

L100 ydL91.44 m

Formula used:

For length calculation, the relation between length and relativistic factor is

L0γL

γL0L

Relativistic factor is

γ11v2c2

Velocity can

vc1+

To determine

(b)

The answer consistent with the fact that relativistic effects are difficult to observe in ordinary circumstances.
