Question

Q.12. How fast would rocket have to go relative to an observer
for its length to be contracted to 99 % of its length at rest?​

Answer 1

Answer:

Relativistic Length Contraction. One of the peculiar aspects of Einstein's theory of specialrelativity is that the length of objects moving atrelativistic speeds undergoes a contraction along the dimension of motion. ... The amount ofcontraction of the object is dependent upon the object's speed relative to the observer ...

Answer 2

Answer:

Explanation:

We will apply special relativity here,

γ = 1/√(1–V²/c²)  

so, here, γ= original length / length after contraction=1/0.99

=> 1/0.99=1/√(1–V²/c²)

1–V²/c²=0.9801

V²/c²=0.0199

V/c=0.141

=141/100= (14.1%)c
