Two   blocks  are  connected  via  a  pulley,  both  blocks  have  a  mass  of  10.kg.  One  block  rests  on  a  horizontal  surface and  the  other  one hangs  freely by  a  cord which  passes over  a  pulley.  Assume  the  cord  does not  stretch, ignore  mass  of  pulley  and  cord,  therefore  acceleration  is  the  same  for  both  blocks  and  tension  is  the  same  for  both  blocks.  The  hanging  block  moves  down so  the  block  lying on  the  horizontal  surface  moves  to  the  right. What  is  the  acceleration (m/s^2) of  the  blocks  if  the coefficient of  friction  between  the  block  and  the   surface  is   0.50.

Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”
