A rocket takes off vertically from the launchpad with no initialvelocity but a constant upward acceleration of 2.25 m/s2 . At 15.4safter blastoff, the engines fail completely so the only force onthe rocket from then on is the pull of gravity (free fall). a) Whatis the maximum height the rocket will reach above the launchpad? b)How fast is the rocket moving at the instant before it crashes ontothe launchpad? c) How much longer after the engines fail does ittake for the rocket to crash on the launchpad?
