Two masses are support by a cable on a pulley system, as shown in Fig. Q1b. The system can be assumed to be initially at rest. Draw a free body diagram for the system, and state how the acceleration of the 100 kg relates to the acceleration of the 50kg mass. [1 mark] Neglecting axle friction and the masses of the pulleys, determine: i) the acceleration of block A; [4 marks] ii) the velocity of block A after it has moved through 3 m; [3 marks] iii) the time required for block A to reach a velocity of 6 m/s.
