A pursuit spacecraft from the planet Tatooine is attempting to catch up with a Trade Federation cruiser. As measured by an observer on Tatooine, the cruiser is travelling away from the planet with a speed of 0.610 c . The pursuit ship is travelling at a speed of 0.840 c relative to Tatooine, in the same direction as the cruiser.

a) What is the speed of the cruiser relative to the pursuit ship?

    A spacecraft flies away from the earth with a speed of4.90×106 relative to the earth andthen returns at the same speed. The spacecraft carries an atomicclock that has been carefully synchronized with an identical clockthat remains at rest on earth. The spacecraft returns to itsstarting point 365 days (1 year) later, as measured by the clockthat remained on earth. What is the difference in the elapsed timeson the two clocks, measured in hours?

    Observer A on Earth sees spaceship B moving at speed v = 0.600c0 away from Earth and spaceship C moving at the same speed in the opposite direction. Observer A determines that both ships simultaneously sent out a radio signal at 12:00:00 noon and another signal at 12:05:00 p.m., making the time interval A measures between the emission of the signals from each ship ?tA = 5.00 min . Let ?tBB denote the time interval measured on ship B between...

    The spaceship Enterprise 1 is moving directly away from earth at a velocity that an earth-based observer measures to be +0.69c. A sister ship, Enterprise 2, is ahead of Enterprise 1 and is also moving directly away from earth along the same line. The veolcity of Enterprise 2 relative to Enterprise 1 is +0.45c. What is the velocity of Enterprise 2, (in terms of c) as measured by the earth-based observer?

    A 1500kg space ship (including fuel) is travelling through space at 25m/s[away from Earth) To gain a little more speed, the rocket expels 400kg of fuel out the back of the ship at 40.5m/s[toward the Earth] The speed of the ejected fuel is measured relative to the space ship. 17. By the time all of the 400kg of fuel has been ejected, what will be the new speed of the spaceship?
