[2] (b) Two blocks connected by a light cord passing over a small, frictionless pulley, rest on frictionless incline planes as shown in Figure 1.1. 125kg 75kg 609 30 Figure 1.1 Draw a free-body diagram for each of the blocks. ii) Find the acceleration of the blocks. ifi) Find the tension in the cords. [15] 2. [a) Define Simple Harmonic Motion (SHM). [1] (b) For a body moving with simple harmonic motion (SHM). Sketch on the same pair axes, clearly labelled graphs showing the variation with position of: the potential energy of the body. ii) the kinetic energy of the body. iii) the total energy of the body.
