A spaceship is traveling at a speed of 0.398c? What is "gamma"?
A spaceship is traveling at a speed of 0.99989c? What is "gamma"?
How fast, in terms of c, must you be going for "gamma" to equal 2.1?
How fast, in terms of c, must you be going for "gamma" to equal 79.000?
v = speed of the spaceship = 0.398 c
gamma is given as
= 1/sqrt(1 - (v/c)2)
inserting the values
= 1/sqrt(1 - (0.398 c/c)2)
= 1/sqrt(1 - (0.398)2)
= 1.090054
v = speed of the spaceship = 0.99989 c
gamma is given as
= 1/sqrt(1 - (v/c)2)
inserting the values
= 1/sqrt(1 - (0.99989 c/c)2)
= 1/sqrt(1 - (0.99989)2)
= 67.4
given that : = 2.1
1/sqrt(1 - (v/c)2) = 2.1
sqrt(1 - (v/c)2) = 1/2.1
(1 - (v/c)2) = (1/2.1)2
(v/c)2 = 1 - (1/2.1)2
v = c sqrt(1 - (1/2.1)2)
v = 0.88 c
given that : = 79
1/sqrt(1 - (v/c)2) = 79
sqrt(1 - (v/c)2) = 1/79
(1 - (v/c)2) = (1/79)2
(v/c)2 = 1 - (1/79)2
v = c sqrt(1 - (1/79)2)
v = 0.9999 c
