    The diagram below shows a crane moving a heavy load of mass 1.5 x 10^3 kg. The mass of the cable is negligible compared with the mass of the load. When the jib moves round and then stops the load swings and behaves like a simple pendulum, undergoing free oscillations. The oscillation has an amplitude of 5.0 m and period of 8.0 s.
    (i) Explain briefly the difference between a free and a force oscillation. (ii) Calculate the length of the cable. (iii) Determine the maximum acceleration of the load as it swings. (iv) Calculate the force on the load that produces this acceleration. (b) The total energy of the oscillating load is approximately 12 kJ. Sketch a graph showing how the kinetic energy of the load varies with time during one cycle of oscillation. Start your graph at a time when the displacement of the load from the equilibrium position is a maximum. Include appropriate scales on the axes of your graph.

    Please help me with these questions, they are all 2 marks, except iii which is 3 marks.Thank you!
