A military tractor, the force of which on the hook is 15 kN, imparts an acceleration of 0.5 m / s ^ 2

A military tractor, the force of which on the hook is 15 kN, imparts an acceleration of 0.5 m / s ^ 2 to the trailer with a rocket launcher. What acceleration will a tractor that develops a force of 75kN impart to the same trailer?

According to Newton’s second law, acceleration is proportional to the force acting on the tractor. With an increase in the traction force from 15 kN to 75 kN, that is, 5 times, the acceleration will also increase 5 times:
5 * 0.5 = 2.5 m / s2.
