1. 2. (a) (b) (a) (b) i) ii) [2] Two blocks connected by a light cord passing over a small, frictionless pulley, rest on frictionless incline planes as shown in Figure 1.1. i) ii) iii) State Newton's laws of motion. Explain how a Newton is defined from these laws. i) ii) iii) 75kg 60 Figure 1.1 125kg 30 Draw a free-body diagram for each of the blocks. Find the acceleration of the blocks. Find the tension in the cords. Define Simple Harmonic Motion (SHM). 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. the kinetic energy of the body. the total energy of the body. [15] [1]
