1. An object of mass, m, is suspended by two cords connected to a wall and to a 5.0 kg block resting on a table as shown. A coefficient of friction of 0.47 exists between the 5.0 kg block and the table. a) Draw an FBD for block with mass 5.0 kg. Determine the magnitudes of the tension in the horizontal rope (T1) and of the normal force acting on block. (FN).

b) Draw an FBD of point of connection of three ropes. Calculate the tension T2 on the rope that form an angle ? = 320 with the wall. (A /2 marks) (C /3 marks) c) Draw an FBD for unknown mass. Determine the magnitude of the tension in the vertical rope (T3) and the unknown mass. (A /4 marks) (C /1 mark)
