For a safe re-entry into the Earth's atmosphere, the pilots of a space capsule had to reduce their speed from 2.76 E 4 m/s to 1.02 E 4 m/s. The rocket engine produced a backward force on the capsule of 1.88 E 5 N. The mass of the capsule is 3,841 kg. For how long did they have to fire their engine?
