1ST AND 2ND LAWS OF MOTIONIMAT 2025 Q591 / 1
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:
A
F1 = F2 = 2000 N
B
F1 = 30 × 10³ N, F2 = 4000 N
C
F1 = 0, F2 = 4000 N
D
F1 = 0, F2 = 6000 N
E
F1 = 2000 N, F2 = 6000 N
