7.A spaceship is flying with a speed of 0.300c relative to the Earth. The spaceship fires a missile with a speed of 0.600c relative to it. The speed of the missile as measured by an observer on Earth is 0.763c. If we assign the spaceship as reference frame S, the missile as reference frame S', and the Earth as the "event", which of the following is correct?
a) u = 0.600c; vx = 0.300c; v'x = 0.763c
b) u = 0.600c; vx = -0.763c; v'x = - 0.300c
c) u = 0.600c; vx = -0.300c; v'x = - 0.763c
d) u= - 0.600c; vx = 0.300c; v'x = 0.763c

You are on board a spacecar that is flying at 0.500c relative to a pursuing spacemobile. When the spacemobile is 2x106 km behind you (as measured in your frame of reference), it fires a missile with a speed of 0.600c relative to the spacemobile. How many seconds, as measured in your frame, will it take the missile to hit your spacecar? a) 7.88 s b) 7.87 s c) 7.78 s d) 8.78 s

Practice Problem 27.3 SOLUTION A spaceship flies past earth with a speed of 0.980c (about 2.97 x 10 m/s) relative to earth. A crew member on the spaceship measures its length, obtaining the value 400 m. What is the length measured by observers on earth? SET UP The length of the spaceship in the frame in which it is at rest (400 m) is a proper length in this frame, corresponding to lo in We want to find the length...

15 pts) A spaceship flying directly toward Earth at 0.7c launches a missle with a speed (measured m the spaceship) of 0.8c at an angle of 60 (measured from the spaceship and measured relative to the ship-Earth direction). What is the speed of the missle measured by people on Earth and what is the angle of the missle's trajectory relative to the ship-Earth direction as measured by people on Earth?
A spaceship is moving past Earth at 0.99c. The spaceship fires two lasers. Laser A is in the same direction it is traveling, and Laser B is in the opposite direction. How fast will the light from each laser be traveling according to an observer on Earth? Select one: a. The light from Laser A will be traveling at 1.99c, the light from Laser B at 0.010 b. The light from Laser A will be traveling at c, the light...
