A spacecraft descends vertically near the surface of Planet X. An upward thrust of 25.0 kN from its engines slows it down at a rate of 1.2 m/s^2, but if an upward thrust of only 10 kN is applied, it speeds up at a rate of 0.8 m/s^2. Apply Newton's second law to each case, slowing down or speeding up, and use this to find the spacecraft's weight near the surface of Planet X.
