Pepper, the space cat, travels to the Centauri star system 4.5 light-years away (one light-year is the distance light travels in one year) at a speed of 0.90 c. Relative to the Earth's frame of reference, the time it takes Pepper to reach the star system is

Question

Quizplus · Accepted Answer

The time it takes for Pepper to reach the Centauri star system can be calculated using the formula $t = \frac{d}{v}$, where $t$ is the time, $d$ is the distance (4.5 light-years), and $v$ is the speed (0.90c, where c is the speed of light). Thus, $t = \frac{4.5 \, \text{light-years}}{0.90} = 5.0 \, \text{years}$.
