For a proper re-entry into the Earth's atmosphere the pilots of a space capsule must reduce their velocity 2. 0 * 104 m/s to 1. 0 * 104 m/s Their rocket engine produces a thrust of 2. 0 * 106 N. The mass of the ship 3. 0 * 103 kg. assume the fuel mass consumed is negligible compared to the mass of the ship. For how Must they fire their engine? approximately what constant power is needed to push a mass M= 10kg a distance of 2. 0 m up along a frictionless incline of 30 in a time t = 4. 0 s?
