1. The problem statement, all variables and given/known data LOOKING AT PART (c) The ball is traveling at velocity c/√2. The car is traveling at velocity c/√2. Ball is thrown up through the sun roof or something I don't know. 2. Relevant equations 3. The attempt at a solution I don't know how to think about this in 3D. I've done parts (a) and (b) though they're probably wrong so I just want to figure out this piece of the problem at least.
