Hi -

I've struggled my way to answer this question and have reached an answer but would welcome expert view....

Many Thanks,

The figure below shows the position-time graph for a particle in simple harmonic motion. x/m t/'s 0.5 1 1.5 2 2.5 3 3.5 4 Estimate the instantaneous acceleration of the particle when its displacement is *= 2.00 m. Give your answer by entering a decimal number into the empty box below. Your answer should be specified to an appropriate number of significant figures and should NOT include any symbols such as . instantaneous acceleration = m s- Hint: You may find it useful to estimate the period T of the oscillation from the graph, and then find the angular frequency, @
