We have a rocket launched vertically from the ground with a constant upward acceleration. Upon reaching a height of h, it experiences engine failure and the only force acting on it is gravity. Given: $\text{m = 8500 kg, a = 2}\text{.5 m/}\text{s}\text{2}\text{, h = 550 m}$. Obtain the velocity just before the rocket crashes. Air resistance is negligible.

Constant Acceleration.

Consider the rectilinear motion of an element that starts from rest and whose speed squared is proportional to the distance traveled. In such a circumstance, the element is said to experience displacement with constant acceleration.
