Please can you answer as well and explain thank you.

Two boxes (24 kg and 62 kg) are being pushed across a horizontal frictionless surface, as the drawing shows. The pushing force of 43 N is horizontal and is applied to the 24-kg box, which in turn pushes against the 62-kg box. Find the magnitude of the force F that the 24-kg box applies to the 62-kg box.

Fnet = ma

43 = (24+62)a
a = 0.5

^^^ As the same force is applied to both boxes (and they are stick together) they would move with same acceleration.

Now, the force exerted by 24kg box on 62kg box is the same as the force exerted by 62kg box on 24kg box:

F = ma
= 62 * 0.5 = 31N
