Here is the problem: Homer knows that the rocket took 14 seconds to come down from its highest point. This means that the rocket was in the air for about 28 seconds before it hit the ground. Use the following equation from the movie to find out the initial velocity of the rocket in feet per second. s = 1/2at^2 + vt a= -32 t= time in seconds s= altitude in feet v= initial velocity I belive (not too sure) the altitude will be 14x5280 (5280=1 mile in feet) but im not sure wether the time is 14 or 28 seconds. A little help please?
