Max observes a spaceship traveling toward him at 0.75c. He measures its length and finds that the spaceship is 250 m long. The s hip brakes hard and skids to a stop on a nearby airstrip. Max remeasures the spaceship. What length does he find
1 answer:
Answer:
380m
Explanation:
We have the speed of the spaceship v = 0.75c
Max measures contracted length L of the spaceship as it travels
We have been given L = 250m
As this ship stops he is going to get exact length of the ship = Lol
We solve using this formula
L = Lo√ 1-v²/c²
From the formula above we make Lo subject of the formula
When we input values
Lo = 250/√1-(0.75c/c)²
= 250/√1-(0.75)²
= 250/√0.4375
= 250/0.6614
= 377.98
This is approximately 380
