Answer:V = u+v/1+(uv/c²)
Explanation:
Answer:
In our day-to-day experiences we’re used to simple velocity addition of formula.
Let’s say your friend is travelling in a car 80km/hr and you’re travelling with same speed but in opposite directions. You will observe the speed of your friend as 160km/hr . Here, we’ve used the formula
v=u+v
Where, v is relative velocity as per classical mechanics.
Though this formula works at speeds which are very low compared to the speed of light, it doesn’t give very accurate relative speed.
When you move speeds which are closer to the speed of light the accuracy reduces. For this, we’ve to use the relativity addition formula[1].
v=v+u1+v∗uc2
If we put the v and u from your question a
