Answer on Question #63076, Physics / Mechanics | Relativity

A pi meson is moving at a speed of 0.85c relative to a flat surface. The flat surface has a length of 3.2m when at rest on Earth. Calculate the length of the flat surface in the reference frame of the pi-meson.

Find: $l - ?$

Given:

```

v = 0.85 c

l₀ = 3.2 m

```

Solution:

```

l = l₀ $\sqrt{1 - \frac{v^2}{c^2}}$ (1)

Of (1) ⇒ l = 1.69 m

```

Answer:

```

1.69 m

```
