Velocity = (displacement) / (time)
Velocity = (change in location) / (time for the change), and direction of the change
Displacement = (location at the end) minus (location at the start)
Displacement = (461.6 km North) - (zero) = 461.6 km North
Velocity = (461.6 km North) / (44.7 sec)
Velocity = (461.6 / 44.7) km/sec North
Velocity = 10.33 km/sec North
That's right about 23,100 miles per hour ! That rocket is really honkin !
With just a little more oomph, that rocket could go up and NEVER come back. The 'escape velocity' from Earth is 11.2 km/sec, and this rocket already has 92% of it !
