Imagine a landing craft approaching the surface of Callisto, one of Jupiter's moons. If the engine provides an upward force (thrust) of 3048 N, the craft descends at constant speed; if the engine provides only 2057 N, the craft accelerates downward at 0.39 m/s2. What is the weight of the landing craft in the vicinity of Callisto's surface? What is the mass of the craft? What is the magnitude of the free-fall acceleration near the surface of Callisto?
