Ineed figuring this problem out. this is all i was able to do:
h(t) = -16t^2 + h
h(t) = -16t^2 + h(14)
h(t) = -16t^2 + 14

what would i do after this to find "t" ?

Without any equipment, you can see stars that are 2{,}800{,}0002,800,0002, comma, 800, comma, 000 light-years away. by looking through a small telescope, you can see stars that are 3{,}112{,}000{,}0003,112,000,0003, comma, 112, comma, 000, comma, 000 light-years away. approximately how many times as far can you see using a small telescope as without any equipment?
