A car weighing 1500 kg begins to move horizontally with an acceleration of 0.5 m / s2. Its resistance to movement is 500N. Determine the thrust generated by the engine.

Solving the problem by the formula:
F = F1 + F2
F1 = ma = 1500 * 0.5 = 750H
F2 = 500H
F = 1250H – traction force developed by the car
Answer: F = 1250H or 1.25kN
