A cube of mass m1 = 6.8 kg is sitting on top of another cube of the same size and mass m2 = 0.7 kg while they are both in free-fall. Ignoring any air resistance, what is the magnitude of the normal force with which the bottom cube is acting on the top cube?
I've tried multiplying each by gravity(9.8) but nothing I'm doing is giving a correct answer
