Question

   ______days b)How far will it travel during this interval?    ______m c)What fraction of a light year is your answer to part b? A light year is the distance light travels in one year.    ________ of a light year    Note: We know, from Einstein's theory of relativity, that no object can travel at the speed of light. So this problem, while interesting and instructive, is not realistic.

Explanation / Answer

We assume g to be 9.8 v = at + v0 = at since it was at rest v0 = 0 v = at => t = v/a = > t = (3.0x10^8m/s)/(9.8m/s2) = __seconds then convert from ___seconds to days. Since there is constant the average velocity would be the average of beggining and ending speed which is (3x10^8)/2 m/s= 1.5x10^8 m/s so distance traveled = Va x t = _____m C = velocity of light Distance = (C/2) x t now if you state t in year form you'll have the answer, t = ___year, then you divide by 2 to get light years.
