A 1500kg space ship (including fuel) is travelling through space at 25m/s[away from Earth) To gain...
1. A ship is travelling away from Earth at .9 c relative to us.. A year (on the ship) into the journey some people get sick of space travel and decide to go back home. They leave in a shuttlecraft travelling at .8 c relative to the ship. A. How fast is the shuttlecraft moving relative to the Earth? B. How long was the ship travelling in Earth time? C. How far has the ship gone from the perspective of...
6) Some time, At, after a rocket blasts off from the surface of Earth, it is travelling at a constant speed, and its instantaneous mass (including fuel) is M 20,000 kg. The gas ejected out the back of the rocket is moving at a relative velocity of 1,200 m/s (downward) with respect to the rocket. You may assume that the rocket is still very close to the surface of the Earth, and that air resistance is negligible. A) What is...
A 65kg astronaut (including spacesuit and equipment), is floating at rest a distance of 15m from the spaceship when she runs out of oxygen and fuel to power her back to the spaceship. She removes her oxygen tank (3.0 kg) and flings it away from the ship at a speed of 15 m/s relative to the ship.At what speed relative to the ship does she recoil toward the spaceship? How long must she hold her breath before reaching the ship?
Amanda pilots a space ship away from earth at a speed of 0.810c. At some moment she sends a light pulse toward earth. Exactly one year later she sends another pulse toward earth. (a) As measured in an inertial frame in which the earth is at rest, what is the difference in time between the generation of the two pulses? (b) What is the difference in time between detection of the two pulses on earth? Treat the earth as stationary,...
Suppose a spaceship heading directly away from the Earth at 0.75c can shoot a canister at 0.35c relative to the ship. Take the direction of motion towards Earth as positive. Randomized Variables V1 = 0.75c V2 = 0.35cPart (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)?
Suppose a spaceship heading directly away from the Earth at 0.65c can shoot a canister at 0.25c relative to the ship. Take the direction of motion towards Earth as positive. Randomized Variables V1 = 0.65 c V2 = 0.25 cPart (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 rocket traveling 1950 m/s away from the Earth at an altitude of 6400 km fires its rockets, which eject gas at a speed of 1300 m/s (relative to the rocket). If the mass of the rocket at this moment is 2.65×104 kg and an acceleration of 1.6 m/s2 is desired, at what rate must the gases be ejected? The answer is not 132.19 it is coming up wrong.
Review Constants Periodic Table Part A A 75-kg astronaut (including spacesuit and equipment) is floating at rest a distance of 15 m from the spaceship when she runs out of oxygen and fuel to power her back to the spaceship. She removes her oxygen tank (3.0 kg) and flings it away from the ship at a speed of 15 m/s relative to the ship. At what speed relative to the ship does she recoil toward the spaceship? Express your answer...
A 61kg astronaut (including spacesuit and equipment), is floating at rest a distance of 10 m from the spaceship when she runs out of oxygen and fuel to power her back to the spaceship. She removes her oxygen tank (3.0 kg) and flings it away from the ship at a speed of 15 m/s relative to the ship. PART A: At what speed relative to the ship does she recoil toward the spaceship? My attempt: m1V1=m2V2 (3kg)(15m/s) = (61kg)(V2) 45...
piloting a state-of-the-art spaceship to α Centauri, which is a star about 4 lightyears away as measured from Earth. Your ship cruises at a speed of 0.6c. For this problem, you can assume that Earth and a Centauri are at rest with respect to each other. At your journey's midpoint, you decide to send a souvenir package to your folks back home. You launcha probe back to Earth at a speed of v 0.8c from your perspective. a. How long...
