Ok this might seem silly but I'm not sure if I misread something or I'm totally blanking out example 1.14 asks what is the range for a projectile launched at 45 degrees with a flight time for 3 sec, the answer goes and it takes 1.5 sec to reach the apex t=Vo/a understood that so 1 second covers 5m ( honestly not sure where the 5 m came from anyways so 1 sec = 5 , 2 sec = 20 so 1.5 sec = 11-12 m the range for 45 is ( 4times the maxim height?
on the previous page it says the max height is h ( only with a 90) max range is 2H with ( 45)
soooo why isnt the range for the 45 in the question 2 times ( 11-12) where did the 4 come from am I missing something real simple here?
