Document Summary
Two blocks are connected by an inextensible massless string over a massless pulley with a frictionless axle as shown in the gure. The block with mass m1 slides on a frictionless horizontal table. The block with mass m2 is suspended by the string and falls with an acceleration a. The tension in the string is t : (3 points) apply newton"s 2nd law and write the equation of motion for the block on the table in the horizontal direction. The forces acting on the block on the table are a downward weight force w , and upward normal force n , and a tension force t parallel to the string. The block has acceleration a along the table (it is connected to the hanging block, which has acceleration a, by an inextensible string). By newton"s 2nd law, the sum of the forces in the horizontal direction equals m1 times the horizontal acceleration of the block on the table (a).
