A spaceship in space sweeps stationary interplanetary dust. As a result, its mass increases at a rate dM(t)/dt = bv2(t), where v(t) is its instantaneous velocity. The instantaneous acceleration of the satellite is:
(1) - bv3/2M(t)
(2) - bv3(t)
(3) -2bv3/(Mt)
(4) - bv3/(Mt)

(4) - bv3/(Mt)
Explanation:
F = V(dm/dt)
a = F/M = - bv3/(Mt)
