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 10.0 kN is applied, it speeds up at a rate of 0.80 m/s^2.(adsbygoogle = window.adsbygoogle || []).push({});

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.

I am completely confused. Any help would be appreciated.
