| **If a trolley weighing 350 kg moves along horizontal rails with an acceleration of 0.15 m / s² with a resistance force of 12 N, then the horizontal force under which the trolley moves is ..**

According to Newton’s second law, we find what the resulting force acts on the trolley Fres = ma = 350 * 0.15 = 52.5N

Then the traction force of the trolley is Fres + Fc = 52.5 + 12 = 64.5N
