Homework Statement
A spaceship moves with a velocity 0.75c xhat with respect to the earth. The ship releases a probe with a velocity 0.75c yhat relative to the ship. What is the velocity of the probe as viewed on earth, magnitude and direction?
Homework Equations
The velocity-addition formulae for all three spatial directions
The Attempt at a Solution
I think that the velocity observed in the x direction of the probe will just be 0.75c, but I am having trouble wrapping my head around finding the velocity in the other directions. I know the velocity is changed due to the time dilation but cannot find the necessary equations to use. I think we are supposed to use 4-vectors
