with respect to the earth, object 1 is moving at speed 0.90c to the right. With respect to the earth, Object 2 is moving at speed 0.90c to the left. How fast is object 2 moving with respect to the object 1?
Solution
Given u = 0.9 c
v = 0.9 c
Speed of object 2 moving with respect to the object 1 is V = (u + v) /[1+(uv/c 2)]
Since they are movint towards each other.
So, V = (0.9c+0.9c) /[1+(0.9cx0.9c /c 2)]
= 1.8 c /[1+0.81]
= 1.8 c /1.81
= 0.994475 c
