Homework Statement
A logo is embedded in a block of glass (n=1.52), 3.2cm beneath the top surface of the glass. The block is put under water so that there is 1.5cm of water above the top surface of the glass. The logo is viewed from directly above by an observer in air. How far beneath the...
Oh! So, Vac = 25/65 = 0.38c and Vcb = 35/65 = 0.58c
So, plugging in:
0.38c+0.54c / 1 + (0.38c)(0.54c)/c^2
= 0.71c, so truck is traveling 49m/s relative to the car? That makes more sense, because it would seem to be traveling faster than it actually is when viewed from the car's frame. Is that...
