2. 2IMAT 2025 Q59

   A car with a mass of 2.0 × 10³ kg travels in a straight line at a constant speed on a flat road. Its speed is 15 m/s. At a certain moment (t = 0) it accelerates with a constant acceleration of 2.0 m/s², in the same direction as the velocity. The constant friction force is 2000 N. The forces F1 and F2 exerted by the engine in the first and second segments, respectively, are:
   1. AF1 = F2 = 2000 N
   2. BF1 = 30 × 10³ N, F2 = 4000 N
   3. CF1 = 0, F2 = 4000 N
   4. DF1 = 0, F2 = 6000 N
   5. EF1 = 2000 N, F2 = 6000 N
