A mass of 0.3 kg is suspended from a spring of stiffness 200 N m–1. If the mass is displaced by 10 mm from its equilibrium position and released, for the resulting vibration: Plot a graph of acceleration against displacement (x) (for values of x from x = –10 mm to x = +10 mm) Hugely struggling to plot and draw this graph. Have been reading about a formula to give values for the acceleration but this formula is giving me numbers which seem way off. Formula: -(w^2 times displacement) So, -25.81^2 x 0.1= -66.61561??? Am I on the right track or miles off?? First post and any help is greatly appreciated!
