Suppose a spaceship heading directly away from the Earth at 0.75c can shoot a canister at 0.25c relative to the ship. Take the direction of motion towards Earth as positive. Randomized Variablesv1 = 0.75 c v2 = 0.25 c Part (a) If the canister is shot directly at Earth, what is the ratio of its velocity, as measured on Earth, to the speed of light? Part (b) What about if it is shot directly away from the Earth (again, relative to c)?
