A rocket takes off vertically from the launch pad with no initial velocity but a constant upward acceleration of 2.25 m/s^2. At 15.4 s after blastoff, the engines fail completely so the only force on the rocket from then on is the pull of gravity.
A) What is the max height the rocket will reach above the launch pad?
B) How fast is the rocket moving at the instant before the it crashes onto the launch pad?
C) How long after engine failure does it take for the rocket to crash onto the launch pad?
