It takes about 7000 years for light from the eagle nebula to reach us on earth. using this information, and the speed of light given above, calculate how far the eagle nebula is from us in kilometres

note: the speed of light is 3x10^8

28. a stone is projected at a cliff of height h with an initial speed of 42.0 mls directed at angle θ0 = 60.0° above the horizontal. the stone strikes at a, 5.50 s after launching. find (a) the height h of the cliff, (b) the speed of the stone just before impact at a, and (c) the maximum height h reached above the grou
