Question

If a rocket travels with velocity 0.8c and another rocket with velocity 0.5c toward first rocket what is relative velocity

Answer 1

velocity of first rocket with respect to the second rocket is .8c-.5c=.3c and velocity of the second rocket with respect to the first is .5c-.8c= -.3c

Answer 2

Answer:

A rocket engine uses stored rocket propellants as the reaction mass for forming a high-speed propulsive jet of fluid, usually high-temperature gas. Rocket engines are reaction engines, producing thrust by ejecting mass rearward, in accordance with Newton's third law. Most rocket engines use the combustion of reactive chemicals to supply the necessary energy, but non-combusting forms such as cold gas ...
