Answer to Question #71369 in Mechanics | Relativity for Terica Rome

Question

Use the fact that the speed of light in a vacuum is about 3.00 ✕ 108 m/s to determine how many kilometers a pulse from a laser beam travels in exactly 4.6 hour(s).

Answer 1

1 h=3600 s.
Distance is
d=ct=(3.00 ∙ 〖10〗^8 )(4.6∙3600)=4.97∙ 〖10〗^12 m=4.97∙ 〖10〗^9 km.
Answer: 4.97∙ 〖10〗^9 km.
