A rocket takes off vertically from the Launchpad with no initial velocity

A rocket takes off vertically from the Launchpad with no initial velocity but a constant upward acceleration of 2.25 m/s. 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 maximum height the rocket will reach above the launch-pad? b. How fast is the rocket moving at the instant before it crashes onto the launch-pad? c. How long after engine failure does it take for the rocket to crash onto the launch-pad?
