    Solution. We can think about this problem in the following way. First, the rocket can go upward with a constant acceleration a=1.86m/s^2 until its engines stop at an altitude of 161m. We can compute the time T it takes. Then, its engines stop and the rocket will decrease its speed to zero because of the gravity. When its speed ...
