Relativistic addition of velocities problem

[QUOTE="Doc Al, post: 4725409, member: 3546"] Yes. The speed of the truck in the frame of the car is greater than the speed of the truck in the frame of the Earth (since the car is also moving with respect to the earth). Unless [B]both [/B]speeds are much smaller than the speed of light, it's best to use the relativistic formula. (For small speeds, the relativistic formula gives almost the same results as the galilean formula.) [/QUOTE]
