Question

Космический корабль удаляется от Земли со скоростью 0,75с, а затем из него стартует ракета со скоростью 0,75с относительно корабля. Чему равна скорость ракеты относительно Земли

Answer 1

Ответ:

дано V1=0,75*C     V2=0.75*C   V- ?

V=(V1+V2)/(1+V1*V2/C^2=1,5*C/(1+0,5625)=0.96*C

Ответ V=0,96*C

Answer 2

Calculation of Rocket's Velocity Relative to Earth

To calculate the velocity of the rocket relative to Earth, we need to consider the velocities of both the spaceship and the rocket relative to each other and relative to Earth.

Given: - Velocity of the spaceship relative to Earth: 0.75c - Velocity of the rocket relative to the spaceship: 0.75c

To find the velocity of the rocket relative to Earth, we can use the relativistic velocity addition formula:

v' = (v + u) / (1 + (v * u / c^2))

Where: - v' is the velocity of the rocket relative to Earth - v is the velocity of the spaceship relative to Earth - u is the velocity of the rocket relative to the spaceship - c is the speed of light

Substituting the given values into the formula, we have:

v' = (0.75c + 0.75c) / (1 + (0.75c * 0.75c / c^2))

Simplifying the equation:

v' = (1.5c) / (1 + (0.5625))

v' = (1.5c) / (1.5625)

v' = 0.96c

Therefore, the velocity of the rocket relative to Earth is 0.96c.

Please note that the above calculation assumes that the velocities are non-relativistic and that the speed of light (c) is approximately 299,792,458 meters per second.
