Full Answer

For example, if a 45 kg person and a 62 kg person are both accelerating at 2 m/s^2, the 62 kg person exerts a greater force than the 45 kg person. Similarly, if both people are 62 kg and one of them is accelerating at 2 m/s^2 and the other at 3 m/s^2, the person accelerating at 3 m/s^2 has a greater force than the person accelerating at 2 m/s^2.
