How long does it take for a space shuttle to reach 17000 mph?

Answer 1

It takes 8 minutes, 31 seconds from launch to MECO (Main Engine Cut Off) for NASA's STS (Space Transportation System) fleet of Space Shuttles to achieve an initial elliptical orbit velocity of about 17,500 mph at an altitude of approximately 69 statute miles. It is interesting to note that this velocity includes an acceleration of about 16,550 mph relative to the launch point at the Cape, with the rotation of the earth at Florida's latitude contributing about another 975 MPH. Further burns of the OMS (Orbital Manuevering System) main engines to round the orbit to it's usual 185 mile distance from earth's surface.
