Suppose a particle called a kaon is created by cosmic radiation (high-energy protons of unknown ori striking the atmosphere. The kaon moves by you at 0.989c, and it lives 1.238 x 10-³s when at res relative to an observer. How long does it live as you observe it? As you observe it, they live for 8 x 10 S.

Suppose a spaceship heading directly away from the Earth at 0.85c can shoot a canister at 0.35c relative to the ship. Take the direction of motion towards Earth as positive.Randomized Variablesv1 = 0.85 cv2 = 0.35 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)?
(a) All but the closest galaxies are receding from our own Milky Way Galaxy. If a galaxy 12.0×109 ly ly away is receding from us at 0. 0.900c , at what velocity relative to us must we send an exploratory probe to approach the other galaxy at 0.990c , as measured from that galaxy? (b) How long will it take the probe to reach the other galaxy as measured from the Earth? You may assume that the velocity of the other galaxy remains constant. (c) How long will it then take for a radio signal to be beamed back? (All of this is possible in principle, but not practical.)
