For a safe reentry into Earth's atmosphere, the pilots of a space capsule must reduce their speed from 2.60 × 10⁴ m/s to 1.10 × 10⁴ m/s. The rocket engine produces a backward force on the capsule of 1.60 × 10⁵ N. The mass of the capsule is 3410 kg. For how long must they fire their engine? Ignore the change in mass of the capsule due to the expulsion of exhaust gases.
