1. A block with 250 g mass is attached to a massless string passing around a massless pulley as shown in the figure. The other end of the string is fixed to a rigid wall. Suppose the pulley is moved in horizontal direction with a force of 0.1 N. Consider surface and pulley to be frictionless. [5 pts] (a) If the pulley is displaced by 10 cm, the block will be displaced by (b) The acceleration of the block is
