    A satellite in a force free space sweeps stationary interplanetary dust at a rate (dM/dt) = ?v. The acceleration of satellite is
    (a)    (-2av^2)/M
    (b)    (-av^2)/M
    (c)    (-av^2)/2M
     (d)    -av2

Question

A satellite in a force free space sweeps stationary interplanetary dust at a rate (dM/dt) = ?v. The acceleration of satellite is (a) (-2av^2)/M (b) (-av^2)/M (c) (-av^2)/2M (d) -av2

Navjyot Kalra · Answer

(b) Thrust on the satellite, F=(-vdM)/dt = -v(av)=av^2 Acceleration F/M=(-av^2)/M
