Before the engines fail , the rocket's horizontal and vertical position in the air are
and its velocity vector has components
After , its position is
and the rocket's velocity vector has horizontal and vertical components
After the engine failure , the rocket is in freefall and its position is given by
and its velocity vector's components are
where we take .
a. The maximum altitude occurs at the point during which :
At this point, the rocket has an altitude of
b. The rocket will eventually fall to the ground at some point after its engines fail. We solve for
, then add 3 seconds to this time:
So the rocket stays in the air for a total of .
c. After the engine failure, the rocket traveled for about 34.6 seconds, so we evalute for this time
