A satellite in force-free space sweeps up stationary interplanetary dust at a rate dM/dt = αv, where M is the mass and v is the velocity of the satellite, and α is a constant. What is the deceleration of the satellite?

Answer: (C)

Solution

Treating the satellite and the dust it incorporates as an isolated system (the dust was initially at rest, and there is no external force): d(Mv)/dt = 0 ⟹
