Space Shuttle launch The mass of the Space Shuttle at launch is about 2.1 X 10⁶ kg. Much of this mass is the fuel used to move the orbiter, which carries the astronauts and various items in the shuttle’s payload. The Space Shuttle generally travels from 3.2 X 10⁵ m (200 mi) to 6.2 X 10⁵ m (385 mi) above Earth’s surface. The shuttle’s two solid fuel boosters (the cylinders on the sides of the shuttle) provide 71.4% of the thrust during liftoff and the first stage of ascent before being released from the shuttle 132 s after launch at 48,000-m above sea level. The boosters continue moving up in free fall to an altitude of approximately 70,000 m and then fall toward the ocean to be recovered 230 km from the launch site. The shuttle’s five engines together provide 3.46 X 10⁷ N of thrust during liftoff.

Which number below is closest to the average vertical acceleration of the shuttle during the first 132 s of its flight?
