Answer #1

L= length of a moving spaceship is =29.6 m

where c= speed of light

Lets the speed of the spaceship =v

then we know the formula

the speed of the spaceship =v =0.103c

ANSWER = 0.103c

The proper length of one spaceship is three times that of another. The two spaceships are traveling in the same direction and, while both are passing overhead, an Earth observer measures the two spaceships to have the same length. If the slower spaceship is moving with a speed of 0.34c, determine the speed of the faster spaceship.

An 88.0 kg astronaut is working on the engines of a spaceship that is drifting through space with a constant velocity. The astronaut turns away to look at Earth and several seconds later is 28.2 m behind the ship, at rest relative to the spaceship. The only way to return to the ship without a thruster is to throw a wrench directly away from the ship. If the wrench has a mass of 0.300 kg, and the astronaut throws the...
