Two boxes are sitting side on a frictionless surface. The box on the left has a mass of 11kg and the box on the right has a mass of 17kg. If a 90-N force pushes on the 11-kg box from the left, what is the force exerted on the 17-kg by the 11-kg box?

A) 55 N

B) 43 N

C) 68 N

D) 35 N

2. Relevant equations

F=ma

3. The attempt at a solution

F=MA

90=(11+17)a

a= 3.2 m/s^2

Since you have to find out the force exerted by the 11-kg box

F=11(3.2)

F=35N

This was a question on a quiz. All my friends got 55N.
