@pcSuarez I will help you through it...

 After one second:
|dw:1363377939546:dw|

Now you know the angle is 19 degrees, and you know the hypotenuse is 239, so now you can calculate the opposite side with trig...
What will that be for 239 feet (1 second)?

THis would actually help a bit: http://answers.yahoo.com/question/index?qid=20110511072851AAidWoN Solution: 192.4 x 239 = 45983.6 45983.6 sin(19 = 14970 So it would take 192.4 seconds to reach the altitude of 14970.
