Question
Two blocks are being pushed along an incline. Block A weighs 7.00 kg and block B weighs 14.00 kg. The
coefficient of non-sliding friction between block B and the surface of the incline is 0.200 and the coefficient of
sliding friction is 0.1000. Assume that the coefficient of friction between the two blocks are too high to cause
sliding between the two blocks. The applied force is 185 N.
