Answer #1

a) Velocity of Spaceship: 0.80 length in reest freame, do = 200m let observed length be= l. So by length contreaction formulaD A 100 Ą | I À 2 V 5/ V100 - so .51c? > V = 0.71410 2. 1424x108 m/s so velocity = 2.14 24 x 10 9 m/s - 0.71410

    Objects traveling at relativistic speeds will appear to a stationary observer as shorter, as- suming that it is parallel to the direction of its motion. Using the equation for Lorentz contraction, find the following, where c is the speed of light: a) A spaceship is traveling with a velocity 0.8c. If it is 200m long in its rest frame (when the object is not moving), how long do you observe it to be? Assume that you can see the entire...
