Question

As of 2012, all of the shuttles in NASA's space shuttle program have been retired. When they once launched, a space shuttle (mass = 2.03 ✕ 10⁶ kg) would lift off as the thrust of its three main engines was suddenly augmented by the firing of the solid rocket boosters at t = 0 s. Suppose the magnitude of the shuttle's acceleration is given by a = 2.80t + 0.390t² − 0.125t³, where a is in meters per second squared and t is in seconds, in the first few seconds after liftoff. What is the change in the kinetic energy of the space shuttle during the first 2.45 s after liftoff in this scenario? In J
