Question

A spaceship is measure to be 100m long (l.) while it is at rest with respect to an observer
if these spaceship fly by observer with speed of 0.99c (v) what length will be observed by observer. Find L = ?

Answer 1

Answer:

Explanation:

=> Here, A spaceship is measure to be 100m long (l.) while it is at rest with respect to an observer.

∴ L₀ = 100 m  

=> these spaceship fly by observer with speed of 0.99c

v = 0.99 c

length L will be observed by observer = ?

Let's use the formula for length contraction to calculate the length of spaceship:

L = L₀√1-v²/c²

L=100√1- 0.99²

L = 100 * 0.141

L = 14.1 ≈ 14 m

Thus, the length of spaceship observed by observer will be approx 14 m.

Answer 2

Answer:

1. time measure by the earth based clock corresponding to 1 day measured by the spaceship clock
