Imagine a landing carft approaching the surface of Callisto, one of Jupiture's moons. If the engine provides an upward force (thrust) of 3260 N, the craft descends at constant speed; if the engine provides only 2200 N the craft accelerates downward at .39 m/s^2. a) What is the weight of the landing craft in the vicinity of Callisto's surface? b) what is the mass of the craft? c)What is the magnutide of the free-fall acceleration near the surface of Callisto?

I need help. I can't figure out what to do I am confused. a) is 3260 N b) is 2.7 X10^3 kg c) is 1.2m/s but I don't know how to get these answers.

a) Since 3260 N thrust provides a constant velocity (presumably they are talking about near Callisto's surface), then it equals the weight. W = 3260 N
b) The mass can be obtained from
m = F/a, where F is the net force when a = 0.39 m/s^2. F = 3260 - 2200 = 1060 N in that siuation, so m = 1060/.39 = 2.72*10^3 kg
c) Free-fall acceleration = W/m
