Homework Equations
$$F=ma$$
$$r \times F = I \alpha $$
The Attempt at a Solution
Denoting the forces at the back wheel with a 1 and front wheel with a 2 and calculating the torques around the CoM I have
$$F-f_1-f_2 = mA$$
$$N_1 + N_2 -mg = 0$$
$$hf_1 + h_f2 - hF +bN_1-aN_2=0$$
with $$f_i = \mu_i N_i$$
So just using this I can't seem to solve for A in terms of mu and g. I have some questions though, is mu the same for both wheels? The also mentions "rolling without slipping", am I meant I incorporate this somehow?, it doesn't give any explicit info and moments of inertias of the wheels so I don't see how.
Any help would be appreciated.
