**calculate the top speed in metres per second****calculate the acceleration in metres per second per second****The acceleration is produced by an unbalanced force. Calculate the thrust produced by the Rolls Royce Orpheus engine for this unbalanced force.****Why is the thrust produced by the engine actually much greater?**
