Homework Statement
Block A sitting on top of block B
has a mass mA = 10 kg and is attached to the wall by mass less string.
Block B, mass mB = 35 kg, is pulled by a force F = 80 N. The surface
under block B is frictionless. If the coefficients of friction for block A
and B areμs = 0.4 and μk = 0.1, then the acceleration (in m/s2) of
block B is
