A 7600 rocket blasts off vertically from the launch pad with a constant upward acceleration of 2.25 and feels no appreciable air resistance. When it has reached a height of 560 , its engines suddenly fail so that the only force acting on it is now gravity.What is the maximum height this rocket will reach above the launch pad? How much time after engine failure will elapse before the rocket comes crashing down to the launch pad? How fast will it be moving just before it crashes?

you need to provide some units before attempting any calculations.
speaking of calculations, what have you gotten so far?
