Conclusion

Suppose that you are on a scooter (or roller-sledge) which has a rocket at the back side. You should analyze how the rocket works and how it helps to move the scooter (or roller-sledge). While there are many possibilities you would be faced with; you should drive the correct conclusions and explain that why you did not ignore the many other possibilities. 
    
    For this assignment you will need to:

1. - Clarify how the rockets work.
2. - Investigate how the rocket helps to move the scooter. 
3. - Explain the physical laws about this motion.
4. - Think about motion in terms of speed and acceleration of the scooter.
5. - Evaluate your results in terms of the speed and acceleration of the
     scooter, total mass (you and your scooter) and so forth.
6. - Prepare a presentation for your classmates.
