Question

(4 points) For a physics project, Miro and Alex had to graph and analyze an example of simple harmonic motion. Alex swung on a swing, and Miro used a motion detector to measure Alex's height above the ground every second, as she swung back and forth. The following table gives the height of the swing over time. Time (s) Height of4 swing (em 189 87 135 173 74 168 142 83 Use sinusoidal regression to determine the equation that approximates this data. Using this equation, estimate Alex's minimum and maximum heights, to the nearest centimetre. pls solve the question. and tell me how to solve it!! thank you very much

pls help

Answer 1

You need to use MATLAB or R to determine the Sinusoidal regression Equation... Here, i have considered the period as 180... So, The output is: Scatter Plot at period = 180 Regression Equation: Regression Equation: HEIGHT = 192.5298. sin(0.0349 TIME + 2.3888) + 23.6972 R - squared: r^2 = 0.0917
