Urgent! Torque to linear acceleration. Please Help!
Q1: A horizontal force F=1000N is applied on a 120kg fridge as shown below. If
friction is present, what is the magnitude of the fridge linear acceleration, and the
magnitude of the normal forces acting at A and B? (hint: this system is not in
static equilibrium, and any possible axis of rotation is obvious moving). .1 k .2 s friction coefficients the fridge only has contact with the floor at A and B.

Torque = r x F
Torque from the horizontal force is 1200, torque from point A is .5(Fna), and torque from point B is in the opposite direction = .5(Fnb)
and Fnb + Fna = Fg = 120 * 9.8
I don't know how do figure this problem out at all, any help would be great.
