1. The problem statement, all variables and given/known data Determine the force acting on a 30kg cart by a 50kg cart if the 30kg cart is pushed into the 50kg cart with a force of 120N. m1=30kg m2=50kg Fa=120N 2. Relevant equations FNET=ma FNET=sigmaF 3. The attempt at a solution Im really confused on where to start here. I was thinking of finding acceleration then substituting in for an FNET equation to find F of 2on1. Any tips on where to start would be helpful thanks.
