A 7500kg rocket blasts off vertically from the launch pad with a constant upward acceleration of 2.20m/s2 and feels no appreciable air resistance. When it has reached a height of 595m , its engines suddenly fail so that the only force acting on it is now gravity.
[1]What is the maximum height this rocket will reach above the launch pad?
[2]How much time after engine failure will elapse before the rocket comes crashing down to the launch pad?
[3]How fast will it be moving just before it crashes?
