During a launch, the space shuttle typically experienced an average acceleration of about 11.1 m/s2 while the solid rocket boosters (SRBs) burned. The SRBs started burning while the shuttle was at rest on the launch pad. If the SRBs contained enough fuel to burn for 127 seconds, what was the velocity of the shuttle after the SRBs ran out of fuel (at which point they would separate from the shuttle and fall into the ocean)?

Solution

velocity v = average acceleration*time  =a*t

velocity v = (11.1 m/s2 )( 127 s ) = 1409.7 m/s
