In the system shown in figure. A horizontal force Fx with a magnitude of 100N acts on object of mass m2=6.15kg. The horizontal force is frictionless. ( Picture- a flat table with mass m2 connected with a string to a pulley and mass 1 hangs off the table.) question...1. if mass 1= 4.35kg what is the magnitude of acceleration of the two objects. 2. find the magnitude of tension in the string
