1. The problem statement, all variables and given/known data Three blocks are placed onto a frictionless horizontal surface. These blocks are side by side and are in contact with each other. Let m1=2m2=5m3. Answer the following exercises. a)If a force is applied to m1, then show that i)Fa = 17/2m3a ii)F12 = 7/2m3a where F12 is the contact force of mass 1 on mass 2 iii)F23=m3a 2. Relevant equations F=ma 3. The attempt at a solution Fx1=m1a Fx2=m2a Fx3=m3a Fa-F21-F31=m1a F12-F32=m2a F13+F23=m3a Fa=m1a+F21+F31 F12=m2a+F32 F13=m3a+F23 Fa=m1a=(m2a=F23)=(m3a-F32) Fa=m1a=m2a=m3a I'm not quite sure if this is the way to even go about it. Any help with this would be greatly appreciated.
