a.)upon liftoff, a rocket flies through the air with a constant acceleration. after 5.0s, its velocity is 11.1 m/s. if you assume that the rocket started with zero velocity, what is its acceleration?

b.) given the same acceleration from (a) what was the rockets velocity 15s after liftoff, and how far has it traveled since liftoff?

Expert Solution

For the last part of the question, I used two formulas and I got the same answer. In case of second equation you don't need time and in case of third equation, you don't need final velocity. Some other question, you 'll not get all data. So depending on your question or given data, you can use any one of those equations.

An airplane is flying at a constant horizontal velocity of 184.5 m/s and drops a rocket. The rocket falls for 10.24 s without air resistance and under the influence of gravity only, and then fires its thrusters. From the moment the thrusters are one, the rocket has a net acceleration of 5.481 direscted 30.21 degrees above the horizontal.
