A rocket of 7700 blasts off vertically from the launch pad having a constant upward acceleration of 2.35 and feels no appreciable air resistance. If it has reached a height of 550, its engines rapidly fail so that the just force acting on it is now gravity.
(i) Determine the maximum height this rocket will reach above the launch pad?
(ii) Determine how much time after engine failure will elapse prior to the rocket comes crashing down to the launch pad?
(iii) Determine how fast will it be moving just before it crashes?
