You are on an interstellar mission from Earth to the distant star Sirius, which is 8.7 light years away. Your spaceship can travel with 70% the speed of light and has a cylinder shape with a diameter of 6 meters at the front surface and a length of 25 meters. You have to cross the interstellar medium with an approximated density of 1 hydrogen atom/m^3. (a) How long does it take for your spaceship to reach Sirius? (b) What is the mass of interstellar gas that collides with your spaceship during the mission? Note: Use 1.673 x 10^27 kilograms as proton mass.

Imagine you are riding on a yacht in the ocean and traveling at 20 mph. you then hit a golf ball at 100 mph from the deck of the yacht. you see the ball move away from you at 100mph, while a person standing on a near by beach would observe your golf ball traveling at 120 mph (20 mph + 100 mph). now imagine you are aboard the hermes spacecraft traveling at 0.1c (1/10 the speed of light) past mars and shine a laser from the front of the ship. you would see the light traveling at c (the speed of light) away from your ship. according to einstein’s special relativity, how fast will a person on mars observe the light to be traveling? a) 0.1c (1/10 the speed of light) b) c (the speed of light) c)1.1c (c+0.1c)
