Answer:
33.16N
Step-by-step explanation:
The 46 N force is causing both boxes to accelerate. To determine the acceleration, we are going to use Newton's laws of motion
F=m*a --> a=F/m
You know that the Force is 46 and the mass is the sum of both boxes (cause you are moving the two of them)
a =46 ÷ (24 + 62) = 46 ÷ 86
This is approximately 0.535 m/s. This is the acceleration of both boxes. To determine the force that the 24-kg box applies to the 62-kg box, you use the newton's law of motion. But now you know the acceleration and the mass
F=m*a=62*0.535m/s=33.16 N
