a he he e? JedW 84. N As of 2012, all of the shuttles in NASA's space shuttle pro- M 11010 mono gram have been retired. When they once launched, a space Runo shuttle (mass = 2.03 X 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 shuttle's accelera- tion is given by a = 3.00t + 0.330t² - 0.100t³, 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 3.50 s after liftoff in this scenario? MO
