4.1 Simple harmonic motion 1a. [4 marks] This question is about simple harmonic motion (SHM). The graph shows the variation with time of the acceleration of an object X undergoing simple harmonic motion (SHM). Determine the maximum displacement of X. Give your answer to an appropriate number of significant figures. Markscheme use of ; or or ; } (allow answers in the range of T = 7.8 to 8.0 (s) or = 0.785 to 0.805 (rad s)) ; (allow answers in the range of 4.0 to 4.25 (m)) two significant figures in final answer whatever the value; Award [4] for a bald correct answer. Examiners report Similarly, this was well done. Most appreciated the need to truncate the final answer to a sensible number of significant digits (two in this case). 1b. [2 marks]
