A 10,000-kg rocket blasts off from earth with a uniform upward acceleration of 2.00 m/s² and feels no air resistance. The upward thrust force its engines must provide during this acceleration is closest to A) 20,000 N. B) 980,000 N. C) 118,000 N. D) 78,000 N.

The thrust force must overcome both the gravitational force and provide the additional force for the upward acceleration. The gravitational force is 10,000 kg * 9.8 m/s² = 98,000 N. The additional force for acceleration is 10,000 kg * 2 m/s² = 20,000 N. Therefore, the total thrust force is 98,000 N + 20,000 N = 118,000 N.
